The fertile Midwest and Great Plains are often called the "breadbasket of the world," and it’s no exaggeration—U.S. farms produce more than $500 billion in goods each year.

While corn, soybeans, beef, and dairy dominate overall output, the sector supports a wide array of other crops and livestock. It also drives innovation in precision machinery, fertilizer development, and agricultural technology that shapes global food production.

1. Gainesville, Georgia - Chicken Capital Chaos

In Gainesville, the self-proclaimed "Poultry Capital of the World," you'd better not even think about using a fork to eat fried chicken. That's right— this town passed a law in 1961 making it illegal to consume chicken with anything other than your bare hands . The ordinance was originally a publicity stunt to promote the town's poultry industry, but it's technically still enforceable today.

2. Wilbur, Washington - Riding Ugly Horses Prohibited

The tiny town of Wilbur takes civic beauty seriously—so seriously that they've outlawed riding an ugly horse down the street . The big question, of course: who gets to decide what constitutes an ugly horse? There's no official equine beauty standard outlined in the ordinance, leaving enforcement entirely up to interpretation.

3. Pocatello, Idaho - Smiling is Mandatory

Feeling grumpy? Don't bring that frown to Pocatello, Idaho, where a 1948 ordinance made it illegal not to smile in public . The law was passed during a time when city leaders wanted to promote a more positive, welcoming atmosphere in their community. Technically, walking around with a scowl on your face could get you in trouble with the law, though enforcement has been, shall we say, lax.

4. Carmel, California - High Heels Require a Permit

Fashionistas beware: in the upscale coastal town of Carmel-by-the-Sea, wearing high heels over two inches tall requires a permit . The law, which dates back to the 1920s, was actually created to protect the city from liability lawsuits. Carmel's charming streets are notoriously uneven and filled with quirky design features, making twisted ankles a real hazard for heel-wearers. Rather than fix the streets, city officials decided to require permits for anyone wanting to wear stilettos around town.

5. Blythe, California - Must Own Cows

In Blythe, a small desert town along the California-Arizona border, you're required by law to own at least two cows before you can wear cowboy boots in public . This head-scratching ordinance apparently aimed to prevent city slickers from appropriating authentic cowboy culture without earning the right. The logic seems to be that cowboy boots are functional workwear for actual cowboys, not a fashion statement for posers.

The reality is that nobody in Blythe enforces this law, and you'll see plenty of people strutting around in cowboy boots without a single cow to their name. The ordinance has become more of a conversation starter than actual legislation

6. Marshalltown, Iowa - No Horse Eating Fire Hydrants

Marshalltown takes fire safety seriously, which is why they've made it illegal for horses to eat fire hydrants . This bizarre law presumably dates from the days when horses were the primary mode of transportation, though exactly what equine-hydrant-munching incident prompted this legislation remains a mystery.

7. Yamhill, Oregon - Fortune Telling Forbidden

In Yamhill, Oregon, predicting the future is not just frowned upon—it's illegal . This small town of fewer than 1,200 residents has a law explicitly banning fortune telling, palmistry, and other mystic arts. The ordinance dates back to the early 20th century, when such laws were common across America, designed to protect citizens from scam artists and charlatans.

8. Cicero, Illinois - Humming Banned on Sundays

This town has an ordinance that prohibits humming on public streets on Sundays . The law likely originated during a more puritanical era, when Sundays were strictly reserved for quiet contemplation and religious observance. Any form of frivolous noise was considered disrespectful to the Sabbath.

9. Paulding, Ohio - No Cop-on-Dog Biting Allowed

In the small town of Paulding, there's a law that addresses a very specific workplace hazard: it's illegal for a police officer to bite a dog , even in self-defense. Most towns have laws protecting people from dog bites, but Paulding flipped the script and decided dogs needed protection from over-enthusiastic law enforcement.

10

10. San Antonio, Texas - Flirting Forbidden

In San Antonio, using your eyes to catch someone's attention romantically is technically against the law. The city has an ordinance that prohibits flirtation and "offensive ogling" in public places . This Victorian-era law was meant to protect people (particularly women) from unwanted attention and harassment before modern sexual harassment laws existed. The rule specifically mentions making eyes at someone or using hands to communicate romantic interest.

Taxation without representation - District of Columbia

Image: Jen Theodore

The DMV in Washington, D.C., has featured "Taxation Without Representation" on the city's license plates since the late 1990s. This is because people living in D.C. don't have a voting representative in Congress , so, yes, they're taxed without representation.

The reason for this dates back to when the Founders of the country decided that the yet-to-be-built Federal City, located on the Potomac, would operate above and beyond any regional, state, or city politics, remaining completely neutral regarding the laws being created. Therefore, there is no representative in Congress.

The Last Frontier - Alaska

Image: Elijah Macleod

There is not much mystery as to why license plates in Alaska feature the nickname "The Last Frontier." Once, the frontier was the continental West. Once the West was won, Alaska became the last frontier.

Along with this nickname, the license plate also features a flag with stars, which represent the Big Dipper and Polaris (the North Star). They respectively symbolize strength and Alaska's northern location.

Constitution State - Connecticut

Image: Davlat Radjabov

While some people might think that the nickname showcased on the Connecticut license plates is about the document that laid the groundwork for American democracy, the truth is different.

"The Constitution State" in this case refers to a set of local government rules from around the year 1639, called the Fundamental Orders. Similar? Yes, but not the same.

4

The First State - Delaware

Image: Liam Matthews

"The First State," the nickname showcased on Delaware’s license plates, references a fact that the state is proud to boast— as it should: it was the first state to ratify the US Constitution before any other state on December 7, 1787.

The nickname wasn't official until a first-grade class made the suggestion in 2002. As it sometimes happens, kids get it before everybody else.

5

Land of Lincoln - Illinois

Image: Richard Hedrick

Another proud statement showcased on the state’s license plates is printed on every Illinois plate: "Land of Lincoln" refers to the fact that, even though he was born in Kentucky, Honest Abe lived in the state capital, Springfield, from 1837 to 1861.

The 1954 plates were the first to feature this nickname, which continues to be used today.

6

The Crossroads of America - Indiana

Image: Tracy Adams

The state of Indiana has numerous interstates crossing its borders, namely I-65, I-69, I-70, and I-74 , and the nickname on its license plate is a direct reference to this. Actually, as it happens in many instances, this nickname is the state’s motto, which became official in 1937.

The current plate design, which features one of the covered bridges the state is known for, is a little cartoonish but has more character.

Sportsman’s Paradise - Louisiana

Image: Tim Mossholder

Some states have had the clever idea of advertising and promoting their features on their license plates. Cars bearing these signs travel all over the country, making them a perfect advertising vessel.

Such is the case for Louisiana, which is a region abundant with spots to fish and hunt . Its license plate is inscribed with one of the state’s nicknames: "Sportsman’s Paradise."

8

Support Wildlife - Maine

Image: Ashes Sitoula

Another state that attracts visitors with its natural diversity and makes good use of its license plates to promote this is Maine, with its "Support Wildlife" plate. This slogan not only invites people to visit but also advocates for environmental protection. This double function is a great use of space and resources, and it should be copied by other states’ license plates.

9

The Spirit of America - Massachusetts

Image: Beng Ragon

If there is no space for the full motto, why not go with an abbreviation, right? At least that was the reasoning for the good people of Massachusetts. Along with a patriotic color scheme, Massachusetts's license plate features the slogan "The Spirit of America." The phrase is a shortened version of the state's former motto: "The Spirit of Massachusetts is the Spirit of America."

10

Unbridled Spirit - Kentucky

Image: Jen Theodore

The last entry on our list goes to Kentucky and its poetic motto proudly showcased on its license plates. According to local authorities, " Kentucky is a place where spirits are free to soar and big dreams can be fulfilled . We relish competition and cherish our champions for their willingness to push beyond conventional boundaries to reach new heights of success."

In any case, this beautiful statement adorns the license plates of many Kentuckians.
