Seattle: The Seattle Underground

People usually visit Seattle for the seafood, waterfront views, coffee culture, and the famous Space Needle. But underneath the busy sidewalks lies part of the city most tourists never realize exists. Beneath Pioneer Square sits the Seattle Underground, a network of old streets and storefronts buried below modern Seattle.

This area dates back to the Great Seattle Fire of 1889, which destroyed much of downtown. City leaders decided to rebuild the streets one story higher to improve drainage problems that had plagued the city for years. For a while, businesses operated below street level, but eventually this lower level was abandoned. Today, guided tours take visitors through the underground passageways and old sidewalks and mix ghost stories and old city legends with the real story below Emerald City.

Chicago: The Chicago River

Between deep-dish pizza, Wrigley Field, jazz clubs, and the towering skyscrapers, few cities feel more American than Chicago. It’s also home to the magical Chicago River, which, in 1900, actually flowed backwards.

Back in the late 1800s, Chicago faced a dangerous problem. The river carried sewage and industrial waste into Lake Michigan, the same lake supplying the city’s drinking water. Disease outbreaks of typhoid and cholera became increasingly serious, and engineers realized something drastic had to happen. In 1900, after years of planning and digging canals, they built a series of canals and locks, like the prominent Chicago Sanitary and Ship Canal, connecting the Chicago River to the Des Plaines River, forcing the water to flow toward the Mississippi River watershed. That way, they reversed the river’s direction so the contaminated water would flow away from the lake instead of into it. The natural flow was forever altered, but it remains central to city life, especially during St. Patrick’s Day when, according to tradition, it’s dyed bright green every year.

New York City: NYPL hidden apartment

Yellow taxies, Central Park, Broadway shows, and nonstop energy have made New York City feel magical. The Big Apple hides many secrets, and the apartment inside the New York Public Library Main Branch is just one of them.

In 1910, the library superintendent, John Fedeler, and his family moved into a private eight-room apartment tucked inside the library. This was so that someone would always be available to maintain the huge building. With bedrooms, a kitchen, and a living area, a full home is hidden behind doors that most visitors passed by. The family lived there until 1941, when the space was converted into offices and storage areas. However, the library still offers tours where visitors can learn about its history.

Portland: Mill Ends Park

When you think of Portland, you may think of Washington Park or Forest Park. But if you pay close attention, you can also visit Mill Ends Park. At just two feet across, it holds the Guinness World Record as the world’s smallest park.

At first glance, it looks more like a flowerpot than a public landmark, but the story goes back to 1948, when journalist Dick Fagan noticed an empty hole that had been meant for a light pole. Tired of staring at it from his office window, he planted flowers there and jokingly claimed that, since it was so small, it was a park for leprechauns. The joke took on a life of its own, and in 1976, it was dedicated on St. Patrick's Day. Today, it’s a must-do for travelers going through Portland, and locals continue treating it with surprising seriousness.

Houston: The Beer Can House

Everything is bigger in Texas, and Houston is no exception. If you’ve been there, you’ve probably visited NASA, the Museum District, and tried a local barbecue joint. But you’ve probably missed a quirky house hidden among the neighborhoods. Located at 222 Malone St, sits the Beer Can House. The name is self-explanatory, since it’s a house covered with beer cans.

In 1968, John Milkovish decided he was tired of painting and maintaining the exterior of his property. Instead, he began flattening beer cans and attaching them to the house. What started as a hobby slowly turned into a full-blown obsession involving more than 50,000 cans. The house went from being a neighborhood curiosity to a roadside attraction to finally being a protected local landmark in 2001. In 2010, Time magazine even ranked it as one of America's top 50 roadside attractions. True to his Texan blood, John Milkovish built something big.

San Francisco: The Wave Organ

No trip to San Francisco is complete without taking the cable car or a picture at the Golden Gate. But tucked away near the Marina District is an attraction many tourists completely miss. The Wave Organ is a gigantic acoustic sculpture that turns ocean waves into music.

Completed in 1986 by artist Peter Richards, t he installation consists of a series of pipes extending into the bay. As tides rise and waves move through the pipes, they create eerie sounds ranging from soft bubbling to deep echoes. Richards was inspired by recordings of artist Bill Fontana, made of sounds coming from a vent pipe of a floating concrete dock in Sydney, Australia. In 1980, he received a grant from the National Endowment for the Arts and tested the first prototypes during the 1981 New Music Festival. Five years later, he completed this sonic sculpture that runs entirely on nature.

Los Angeles: La Brea Tar Pits

Los Angeles is all about Hollywood, palm trees, and the beaches. But it’s also home to one of the world’s most important prehistoric sites. The bubbling black pools at La Brea Tar Pits have been trapping animals for tens of thousands of years.

Long before Los Angeles was the city it is today, natural asphalt constantly came up from underground. Mammoths, saber-toothed cats, dire wolves, and other Ice Age animals became trapped there, preserving their skeletons remarkably well. Scientists began excavating fossils in the early 1900s, and discoveries continue to this day. The fossils recovered from the site are countless. Visitors can explore the museum for $18 and watch active excavations while surrounded by modern office buildings and traffic.

Seattle: The Giant Shoe Museum

Seattle already has its share of unusual attractions, especially around Pike Place Market, where fishmongers toss salmon through the air, and crowds line up for fresh pastries. But the Giant Shoe Museum, located there, is even stranger. A single exhibit wall dedicated to oversized footwear , the museum works like an arcade peep show. Visitors drop coins into viewing slots to reveal displays featuring enormous boots, giant clown shoes, and other gigantic footwear.

The museum was founded in 1997 by Danny Eskenazi after he became obsessed with his grandfather’s missing item: the shoe of Robert Wadlow, the tallest man in history. He even offered $1,000 to anyone who could find that Wadlow shoe. Sadly, the shoe remains lost, but his obsession led to the discovery of other shoes worn by Wadlow and more footwear that is now displayed in the museum.

Boston: Great Molasses Flood Site

Boston's most popular spots blend colonial and Revolutionary War history with vibrant neighborhoods that feature top attractions like the Freedom Trail, Fenway Park, and the Boston Public Garden. But it’s also home to the remains of a disaster.

In 1919, Boston experienced the Great Molasses Flood. A massive molasses storage tank burst in the North End neighborhood, unleashing more than two million gallons of syrup into the streets. After 21 people lost their lives, the disaster led to stricter construction safety regulations across the country, and the tank was never rebuilt. Today, visitors can still walk through the neighborhood where it happened. There’s no giant syrup wave anymore, thankfully, but plaques and local tours continue telling the story.

Lake Havasu City: The London Bridge

Driving through Lake Havasu City in Arizona, you expect desert landscapes, boating, and blazing summer heat. You probably don’t expect to stumble across a famous bridge from England, especially not the original London Bridge itself.

In 1831, John Rennie designed and opened the London Bridge spanning the River Thames. By the 1960s, the bridge started sinking under the weight of modern cars and traffic. Robert P. McCulloch, founder of Lake Havasu City, saw this as an opportunity and, in 1968, he purchased the bridge for $2.4 million. The bridge was dismantled and reconstructed in the Arizona desert, and completed in 1971. What once connected two sides of London now links mainland Lake Havasu City with Pittsburgh Point that visitors and locals enjoy every day.

Atlanta: The Center for Puppetry Arts

Atlanta is often associated with Southern cooking, a busy airport, and its important role in the Civil Rights Movement. But tucked inside the city is also the Center for Puppetry Arts, which houses the world’s largest collection of Jim Henson’s original Muppets.

The center opened in 1978, when puppeteer Vincent Anthony transformed a former elementary school into a home for puppet arts. From the very beginning, the project had a special connection to Jim Henson himself. He and Kermit the Frog helped inaugurate the center, and over the years, Henson became one of its biggest supporters. The center expanded significantly between 2007 and 2015, adding the permanent Jim Henson Collection and the impressive Worlds of Puppetry Museum. Unlike many museums, this place is hands-on. Guests can watch live performances, explore exhibits from puppet traditions, and revisit characters that shaped generations of childhood memories.

George Washington had wooden teeth

Image: Todd Trapani

Washington suffered from dental problems throughout his adult life and did wear several sets of false teeth. However, he did not wear wooden ones.

They were made from materials like ivory, metal, and springs . The "wood" myth probably comes from the staining of ivory and from 19th-century caricatures.

2

Salem witches were burned at the stake

Image: Sofia Holmberg

We hold the long-standing belief that the accused Salem "witches" were burned like European witch victims.

However, in the Salem (and colonial New England) trials of 1692–1693, convicted witches were almost always executed by hanging ; burning at the stake was not the legal penalty under English law in the colonies.

Paul Revere rode and shouted, "The British are coming!" alone

Image: Mikhaël Noury

He may be riding alone in the Boston statue that represents the dramatic midnight ride in which he warned of the British troop movements.

But in reality, Revere was one of several riders who spread word of the British troop movements; Longfellow’s 1860 poem amplified and simplified the story, including the shouted line, which would have been unlikely among colonists.

4

Betsy Ross designed the first American flag

Image: Heather Newsom

We have heard again and again the myth that Betsy Ross stitched the first Stars and Stripes after being asked by George Washington. In reality, this tale grew from a family tradition promoted more than a century after 1776. Historians have found no contemporary documentation proving that she designed the first official flag.

The flag’s creation was likely more complex and collective. Ross has always remained a folk symbol, but there is no proof that she was the sole designer.

Mrs. O’Leary’s cow started the Great Chicago Fire

Image: raquel raq

The myth: a cow kicked over a lantern in Catherine O’Leary’s barn and caused the 1871 conflagration. The cow story originated in sensational newspaper reporting and later became part of folklore.

Investigations have never produced conclusive proof, and modern historians treat the O’Leary–cow tale as an unfair scapegoating and probably apocryphal. The fire’s precise origin remains a mystery.

6

"Molly Pitcher" was a famous woman who operated a cannon at Monmouth

Image: Foysal Razu

The story of Molly Pitcher, a single heroic woman who supposedly took over a cannon when her husband fell, may have been created to represent several women . The best documented candidate is Mary Ludwig Hays, but the legend also reflects the broader contributions of women who supported troops during the Revolutionary War, with or without having been widowed.

Davy Crockett died fighting to the last at the Alamo

Image: Eric Francis

Did Crockett heroically fight to the death amid hand-to-hand combat at the Alamo? Well, that was indeed the location of his death, but sources conflict about the manner.

Some eyewitness accounts and Mexican records suggest he may have been captured and executed; other accounts describe him dying in combat. The neat heroic portrait was shaped by 19th-century myth-making.

The Declaration of Independence was signed on July 4, 1776

Image: The New York Public Library

It is widely believed that all signers of the Declaration of Independence scribbled their names on it on July 4, which is why we celebrate that date.

Congress adopted the Declaration on July 4, but most delegates did not sign the parchment copy until August 2 of that year (and a few added their names even later). July 4 became the commemorative date for adoption and celebration, not the universal signing day.

9

The Pilgrims’ "First Thanksgiving" centered on a big roast turkey, like today

Image: Tyler Donaghy

No, the 1621 harvest meal at Plymouth did not feature the same turkey-centered feast we picture now.

Accounts mention venison and wildfowl, but the menu and ritual context were very different from modern Thanksgiving dinners. The idea of an annualized, turkey-centered national holiday developed much later (19th century onward).

10

Thomas Edison single-handedly invented the light bulb

Image: Tamas Pap

Many believe that Edison alone invented the incandescent light bulb out of whole cloth. But electric light was the product of decades of work by many inventors (from Humphry Davy to Swan and others).

Edison’s contribution was significant improvements and the critical development of a commercially viable, manufacturable system, but he did not "invent" electric light in isolation.

11

Pocahontas dramatically saved John Smith from execution

Image: EricThriller

The myth holds that Pocahontas heroically rescued Captain John Smith by throwing herself over him at the moment of execution.

Disney may have amplified the romantic and dramatic aspects of this story. John Smith’s account of a dramatic rescue appears in later writings and is debated by historians. Many scholars now interpret the scene as a ritual adoption or a ceremonial act rather than a literal rescue, or they suspect Smith embellished the story.

Florence Trail, Vermont

Image: Rod Long

Intermediate mountain bikers will love this berm-and-jump-filled descent, which can be incorporated into a 5-mile ride at Cady Hill . The Florence Trail is known as the best flow trail in Stowe, and one of the finest trails in the state of Vermont.

Advanced riders seeking to add some swoop and flow to their biking adventures will also find this trail enjoyable.

2

Devil's Den, Arkansas

Image: Oliver Graham

A mountain bike trail with history attached to it, Devil's Den State Park is a hallmark in the Arkansas mountain biking scene. At the very trailhead, a sign proudly declares that the lower area of the park, known as Fossil Flats, was the "Birthplace of Arkansas Mountain Biking" in 1989.

Recently designated as a "Monument Trail," the park underwent renovations to update sections of the historic trail while expanding the network with brand-new segments. Featuring impressive rock formations, jumps, and drops, Devil's Den truly is a biker’s paradise.

Despite being the most remote mountain bike destination in the Lower 48, Copper Harbor is home to some of the highest-quality trails in the nation. The newest additions to the network, located on Rock Solid's privately owned East Bluff mountain, include some of the best trails that have been built in the nation . Among them, the Citrus Tech trail stands out, earning praise from every mountain biker who has ridden it.

4

South Boundary Trail, New Mexico

Image: Richard Hedrick

An epic trail that winds through stunning mountain meadows and aspen groves before descending into the desert town of Taos , the South Boundary Trail features 4,500 vertical feet of downhill riding. However, it’s worth noting that bikers will face 2,000 feet of climbing along the way—but the breathtaking ride more than makes up for the effort.

5

Doctor Park, Colorado

Image: Holly Mandarich

One of the most thrilling descents in the country, the Doctor Park singletrack takes riders on an unforgettable journey. Starting at a high elevation, the trail winds through an alpine meadow , descends into an aspen grove, and continues down into pine forests before reaching a dry, lower-elevation climate zone .

Bikers from across the country and around the world can either shuttle to the top or pedal their way up to experience this incredible ride.

6

The Presidio, California

Image: Tim Trad

California is brimming with bike trails, making it difficult to recommend just one. However, this former military base turned national park stands out with its 25 miles of paved or hard-packed trails. Offering sightlines to the bay, coastal cliffs, beaches, forests, Alcatraz, the city skyline, and, of course**,** the iconic Golden Gate Bridge , it’s an unforgettable biking destination.

7

DuPont State Forest Slickrock, North Carolina

Image: Leslie Cross

The DuPont State Forest is a rarity on the East Coast due to its exposed bedrock trail. The biking experience in the North Carolina mountains offers epic descents, small mountains, and trails that flow nicely on soft rocky terrain , giving visitors a great experience, with the Slickrock (Cedar Rock, Big Rock, and Burnt Mountain) trail being one of its highlights.

8

Alpine Trail, Oregon

Image: everett mcintire

There are many trails named "Alpine Trail" but this one, at least, honors its name. Beginning high in the mountains, it goes downhill on soft and beautiful black dirt . A few open meadows and exposed outcroppings provide brief panoramic views of the Cascade Mountains, before dropping back into the timber for more high-speed ripping.

9

Tahoe Rim and Flume Trails, Nevada

Image: Abhi Verma

The Flume Trail wasn’t originally designed for bicycles—it began as the grade for a water flume that delivered lumber from high in the mountains above Lake Tahoe to the towns below. Today, remnants of the flume are still visible, but the old flume bed has been repurposed for use by mountain bikers and hikers.

10

Osberg Ridgeline Epic, Idaho

Image: Karsten Winegeart

The Osberg Ridgeline Epic isn’t for everyone. While it requires a shuttle to reach the trail’s starting point, bikers are still faced with over 3,000 feet of uphill pedaling. However, on the other hand, that 3,000 feet of climbing rewards riders with 5,500 feet of thrilling descent, along with a 15-mile ridge traverse with amazing views .
