Buffalo, New York / Niagara Falls, Ontario

Here, one of America's most famous natural wonders creates a binational tourist destination that draws millions annually . The Peace Bridge connects the cities, facilitating a relationship that goes far deeper than tourism. Buffalonians regularly cross for theatre performances at the Shaw Festival, cheaper prescription medications, and a lower legal drinking age.

The cultural blending also shows up during matchups between the Buffalo Sabres and the Toronto Maple Leafs. While the rivalry is intense, it reflects a shared Great Lakes identity shaped by decades of cross-border movement. Canadian shoppers have long made Buffalo malls a destination, while Americans enjoy Windsor-style pizza and Tim Hortons coffee on the Canadian side. The accent in this region reflects generations of cross-border mixing and shared Great Lakes culture.

Detroit, Michigan / Windsor, Ontario

Detroit and Windsor form one of the busiest international crossings in North America, connected by both the Ambassador Bridge and the Detroit-Windsor Tunnel. Over 8,000 trucks cross daily, carrying a quarter of all trade between the U.S. and Canada. But beyond commerce, these cities share deep cultural ties : Detroiters pop over to Windsor for Caesar cocktails and Canadian beer, while Windsor residents cross for Red Wings games and shopping at Somerset Collection.

During Prohibition, Windsor became Detroit's not-so-secret supplier, creating smuggling routes and speakeasies that became Motor City legend. Today, you can stand on the Detroit riverfront and see Canada closer than many American suburbs.

Laredo, Texas / Nuevo Laredo, Tamaulipas

Laredo is one of the oldest crossing points on the U.S.-Mexico border, founded in 1755. The city's Washington's Birthday celebration, oddly enough, is one of the largest such celebrations in the country, spanning nearly the entire month of February and including participants from both sides of the border.

The economy here revolves around international trade, with massive amounts of freight crossing daily between the two nations. But beyond commerce, the cultural blend shows up everywhere—in the predominance of bilingual conversations, in restaurants serving cabrito alongside barbecue, and in the way holidays are celebrated with traditions from both countries.

Blaine, Washington / Surrey/White Rock, British Columbia

Blaine sits at the western end of the U.S.-Canada border, where the line literally runs through Peace Arch Park—a unique binational park where families can picnic with relatives from either country without going through customs. The Peace Arch monument itself straddles the border, inscribed with "Children of a Common Mother" and "Brethren Dwelling Together in Unity."

Residents on both sides share a love of hiking, craft beer, and fish and chips. Blaine residents drive to Surrey for groceries at Canadian supermarkets, while British Columbians come south for gas, milk, and Trader Joe's runs . The Cascadia bioregion identity—encompassing B.C., Washington, and Oregon—often feels more meaningful to locals than national boundaries.

5

Derby Line, Vermont / Stanstead, Quebec

Derby Line and Stanstead share the most uniquely porous border in North America . The Haskell Free Library and Opera House was deliberately built straddling the international boundary in 1904, with the stage in Canada and most seats in the U.S. A black line on the floor marks where one country ends and another begins—no passport required.

Several homes and buildings in town sit directly on the border, with front doors in one country and back doors in another. Before 9/11 and increased border security, locals would casually cross back and forth multiple times daily without much thought. While regulations have tightened, the community identity remains binational.

6

Sault Ste. Marie, Michigan / Sault Ste. Marie, Ontario

The "Twin Saults" are literally the same city split down the middle by the St. Marys River and the International Bridge . Founded as a single French missionary settlement in 1668, the community was divided when the border was formalized after the War of 1812. Today, residents on both sides maintain that they're really one town with an inconvenient international boundary running through it.

The Soo Locks on the American side and the Canadian locks create a shared identity around Great Lakes shipping—watching massive freighters navigate the locks is a regional pastime. Hockey culture dominates both sides, with junior leagues and recreational teams mixing Canadian and American players. Families cross the bridge for shopping, dining, and visiting relatives as casually as driving across town.

7

Hyder, Alaska / Stewart, British Columbia

While Hyder sits on the Alaskan Panhandle, it functions like a practical island: with no roads connecting it to the rest of the state, its only lifeline is a two-mile stretch of pavement leading into Stewart, B.C. This forced detour through Canada has effectively turned Hyder into a 'suburb' of its Canadian neighbor, where the border is a formality and the geography is the boss. With a population hovering around 20 people, Hyder has no bank, no post office, and spotty cell service—but it does have Stewart, B.C., just two miles away. The 400 residents of Stewart provide the services Hyder lacks, creating a dependence that makes the border almost irrelevant to daily life .

Hyder runs on Pacific Time rather than Alaska Time, uses Canadian currency, and Canadian area codes. Kids from Hyder attend school in Stewart. The towns share a volunteer fire department and emergency services.

8

Nogales, Arizona / Nogales, Sonora, Mexico

Ambos Nogales—"Both Nogales"—is what locals call this split city where the international boundary literally runs down the middle of town. Before modern border security, people would step back and forth across the line to shop, visit family, or grab lunch.

The American side has a population of around 20,000, while the Mexican side has grown to over 300,000. Despite the size difference, the cultural exchange remains strong. Arizona residents cross for affordable dental care and authentic Sonoran cuisine, while Mexican families come north for shopping at American chain stores. The shared history runs deep—many families have relatives on both sides , and the sense of being one divided community persists despite the increasingly fortified border.

9

San Diego, California / Tijuana, México

The San Ysidro Port of Entry between San Diego and Tijuana is the busiest land border crossing in the Western Hemisphere, with around 70,000 northbound vehicle passengers daily . This constant flow has created a cultural fusion zone where fish tacos meet California beach culture, and where thousands of people hold jobs on one side while living on the other.

Craft beer culture flourishes on both sides, with breweries collaborating across the border. Street art in both cities shares similar styles and themes, while music festivals regularly feature artists from both nations.

10

El Paso, Texas / Ciudad Juárez, México

El Paso and Juárez form one of the world's largest binational communities, with over 2.5 million people living in the combined metro area . Families routinely cross the border for work, school, shopping, and Sunday dinner. The Franklin Mountains provide a stunning backdrop to this bustling cultural exchange, where Tex-Mex cuisine was practically invented and where speaking both English and Spanish isn't just common, it's essential.

The downtown areas of both cities sit so close you can practically wave to someone across the Rio Grande. Street vendors sell elotes and hot dogs side by side, while radio stations broadcast to audiences in both countries simultaneously.

Blockbuster

During the 1980s and 1990s, Friday night often meant one thing for American families: a trip to Blockbuster. Browsing the aisles for a movie, debating what to watch, and grabbing popcorn at the counter became a weekly routine. But nothing lasts forever.

Born in 1985, Blockbuster conquered the massive home-video market with thousands of stores by the late 1990s and early 2000s, catering to families with at-home VCRs. Then technology changed everything. First came DVD-by-mail services like Netflix, followed by streaming, which left Blockbuster struggling. Late fees and inconvenience only pushed more customers away. The company filed for bankruptcy in 2010. Today, just one official store remains in Bend, Oregon, where visitors still stop by for a dose of the video-store era.

2

Kodak

Back in the day, almost every vacation, birthday, wedding, or holiday gathering seemed to include a Kodak camera, or at least a roll of Kodak film. Founded in 1881, Kodak helped keep the moments that filled family photo albums for generations.

From the 1960s through the 1990s, Kodak dominated the world of film and photography. But that success also made the company slow to accept that technology was changing. Ironically, Kodak helped invent one of the first digital cameras in 1975, yet it hesitated to embrace the future. By the 1990s and 2000s, digital cameras (and later camera phones) quickly replaced traditional film. In 2012, the company declared bankruptcy.

3

Pan Am

Long before flying became an everyday experience, Pan American World Airways, better known as Pan Am, was already carrying Americans across the world. It was founded in 1927, and during the 1960s and 1970s, the airline became a symbol of glamorous air travel.

Its famous blue globe logo was instantly recognizable, even to those who rarely flew. But by the late 1970s, rising competition, fuel costs, and financial troubles began weakening the company. After years of mounting losses and debt, Pan Am shut down in 1991. Even so, its fame was such that even today, more than 30 years later, we still remember it.

4

Woolworth’s

Before Woolworth's made the "five-and-dime" famous, shopping in America looked very different. For decades, Americans visited Woolworth’s for everything from toys and school supplies to household goods and everyday essentials. By the 1960s, the brand had become a familiar part of American life.

Created in 1879 by Frank Winfield Woolworth, the chain grew into one of the country’s largest retailers. But in the 1970s, malls and discount giants like Walmart changed the way Americans shopped, and Woolworth struggled to keep up. By the 1980s, the iconic chain was slowly disappearing. Most stores closed during the 1990s, and the Woolworth retail chain officially ended in 1997.

5

Circuit City

Testing giant stereo systems, browsing rows of CDs and video games, and shopping for the newest TV were all part of the experience at Circuit City, once one of America’s biggest electronics chains.

Founded in 1949 by Samuel S. Wurtzel in Richmond, Virginia, as "Wards Company," the retailer adopted the Circuit City name in 1984. During the 1980s, 1990s, and early 2000s, it became the go-to place for Americans buying a TV, stereo, computer, or any electronic device. But like many companies on this list, Circuit City struggled as shopping habits changed and online stores became more convenient. A controversial 2007 decision to lay off thousands of experienced employees further hurt the company’s reputation. Circuit City couldn’t survive mounting losses and closed all remaining stores in 2009.

6

Borders

Remember Borders? Born in 1971, its huge stores, filled with books, music, magazines, and cozy reading spaces, invited customers to spend entire afternoons there.

During the 1990s and early 2000s, the rise of large shopping malls actually helped Borders thrive, turning its bookstores into popular destinations inside malls across the US. But eventually, the company ran into a challenge it couldn’t overcome: online shopping and digital reading. Competitors like Amazon surged ahead, while Borders struggled to adapt and made costly business decisions, including outsourcing its online sales to Amazon for years. The company collapsed financially in 2011 and soon closed all remaining stores.

7

Bugle Boy

In the late 1980s and early 1990s, teenage fashion became almost synonymous with Bugle Boy. Famous across the country for its casual jeans and memorable TV commercials, the brand became a major part of American mall culture and was sold in department stores nationwide.

But fashion never stands still, and brands have to constantly adapt to survive. By the late 1990s, newer youth-oriented labels had taken over with fresh styles that quickly made Bugle Boy seem outdated. Sales began to fall, and after years of struggling to keep up with changing trends, the company closed its stores in 2001.

8

Howard Johnson’s restaurants

During the 1960s and 1970s, a stop at Howard Johnson's was part of the classic American road-trip experience for many families, and that was no accident.

Founded in 1925 in Quincy, Massachusetts, the famous orange-roofed chain reached its peak when America’s expanding highways and booming car culture made roadside travel more popular than ever. But by the late 1970s and early 1980s, the growing popularity of fast-food chains like McDonald's began changing the way Americans ate on the road. Drivers increasingly wanted meals that were faster, cheaper, and more standardized, while interstate highways also redirected traffic away from many older roadside locations. Unlike some other brands on this list, Howard Johnson’s faded away slowly over the decades. The last restaurant finally closed in 2022.

9

Burger Chef

In 1958, a name emerged as one of the pioneers of America’s growing fast-food industry: Burger Chef. By the late 1960s, the chain had more than 1,000 locations across the country and had become one of McDonald's’s biggest competitors.

Long before Happy Meals became famous, Burger Chef helped popularize the idea of marketing meals directly to children with toys and themed publicity. But during the fast-food wars of the 1970s, competition became fiercer than ever. While McDonald’s and Burger King expanded by leaps and bounds, Burger Chef struggled with financial problems and changing consumer tastes. In 1982, the company was sold to Hardee's, which gradually converted most Burger Chef locations into Hardee’s restaurants.

10

Sports Authority

Throughout the 1990s and 2000s, many Americans looking for running shoes, gym shorts, and sports gear headed straight to Sports Authority.

Known for its huge stores packed with athletic apparel, exercise equipment, bicycles, camping gear, and team sports products, Sports Authority became the ideal shopping destination for families and athletes across the US. But as online shopping rapidly changed retail in the 2000s, the company struggled to adapt. Heavy debt from expansion efforts and a slow shift to e-commerce eventually caught up with the chain. Sports Authority declared bankruptcy in 2016 and closed all remaining stores later that year.

What are bills made of?

Unlike other currencies, dollar bills are not made of paper or plastic. U.S. dollar bills are made from a special fabric blend composed of 75% cotton and 25% linen. This mix makes the bills extremely durable and resistant, and they can be folded about 4000 times before tearing.

2

What bills are valid?

Any U.S. dollar bill that was legally printed is valid, no matter how old, as American currency does not have an expiration date. While some bills might not be accepted by businesses of foreign exchange services due to their condition or if they are a discontinued version of the bill, the bills themselves are still valid, and American banks will accept them, though they might take them out of circulation.

3

American leaders

Five bills have a depiction of an American president. The exceptions are the $10 bill, with Alexander Hamilton on the front, and the $100 bill, with Benjamin Franklin. The $1 bill, depicting George Washington, is extremely symbolic: several elements are repeated 13 times as a nod to the thirteen colonies, and it showcases the Bald Eagle and the Eye of Providence as a sign of God watching over America.

4

A change in size

Did you know that dollar bills used to be so big that they were nicknamed "horse blankets"? Original dollar bills were 7.4 × 3.1 inches. In 1929, the Treasury Department reduced the size of bills to 6.14 × 2.61 inches to reduce production costs and materials. Old bills, though still valid, are worth much more as collector items.

5

Uniformity

Besides their value and design, all dollar bills have the same size (6.14 × 2.61 inches), color, and weight (1 gram) , which sets American currency apart from other countries where bills of different values are differentiated by size, color, or both. Why doesn’t the U.S. implement differences among bills? The cost of adapting vending machines, bank drawers, and ATMs to new bill sizes would cost billions of dollars.

6

Hard to copy

Originally, dollars were not green, but black. As time passed, green ink was favored, as it was cheap and did not fade as much as black. The new color also prevented people from using black-and-white cameras to create counterfeit money. Currently, dollar bills are predominantly green, but newer versions also include extra colors, such as pink, orange, or purple.

7

A $100,000 bill?

Have you ever seen a $500 or 1,000 dollar bill? What about a $100,000? Up until 1945, the U.S. Treasury printed $500, $1,000, $5,000, $10,000, and $100,000 notes , in addition to the values currently in use. These higher-value notes were mainly intended for bank and government use, but were sought by criminals as they made it easier to hide large amounts of money. Even though they were officially discontinued in 1969, these notes are still valid, though rare, and they have a high worth as collector's items.

8

No numbers

Unlike bills, American coins have different sizes and colors related to their value. Originally, gold, silver, and copper were used for coins, but modern coins are made of copper, zinc, or nickel. Besides their size and design, the value of each coin is printed in letters, not in numbers , alongside depictions of American presidents.

9

Liberty for all (the coins)

By law, all American coins must include six specific details : the word ‘Liberty’, the name of our country, the national motto "In God We Trust", the oldest American motto "E Pluribus Unum", the value of the coin, and the year. Each coin also includes a mint mark that shows where it was made: "P" for Philadelphia, "D" for Denver, "S" for San Francisco, and "W" for West Point.

10

A global currency

The American dollar is one of the most powerful currencies in the world, acting as a backbone for international trade and finances. It is estimated that two-thirds of the physical dollars in circulation are outside American territory. Besides the U.S. and its territories, eight sovereign nations have the U.S. dollar as their official currency, with several more accepting it as legal tender.
