There's only one

How many states share a border with just one other state? Only one! Do you know which one it is?

Correct! It's Maine. The Pine Tree State, located in the northeastern United States, shares its only state border with New Hampshire to the west. But wait! It also borders Canada (the provinces of New Brunswick and Quebec) to the north and northeast, and the Atlantic Ocean to the east.

Alaska's distance

If someone asked you what the shortest distance is between Alaska and the Lower 48 states, would you know the answer? Most people wouldn't! Well, the average distance between Alaska and the contiguous US is about 500 miles. But that's not the most interesting part. Believe it or not, Alaska is actually closer to Russia than to the mainland United States! At their closest point, Alaska and Russia are separated by just 2.4 miles across the Bering Strait.

The US-Canada border

You probably already know that, at 5,525 miles, the US-Canada border is the longest land border in the world. But there are still some fascinating details about it that many people haven't heard before.

The Haskell Free Library and Opera House (Derby Line, Vermont & Stanstead, Quebec) has an international border inside the building! You read that right: Americans enter through one door, Canadians through another. But be careful! International law requires that you exit through the same door you entered.

The largest freshwater lake

The Great Lakes —Lake Superior, Lake Michigan, Lake Huron, Lake Erie, and Lake Ontario— are one of the natural wonders of North America, and they also hold a world record!

That's right! The largest freshwater lake in the world by surface area is right here in North America. We're talking about Lake Superior, which is shared by both the United States and Canada.

The most densely populated state

Since New York City is the most densely populated city in the country, many tend to believe that, as a result, New York State is the most densely populated. However, that's not the case.

The most densely populated US state is actually New Jersey! Its small size, combined with the large population in its urban areas and its proximity to New York City, has earned The Garden State this title.

The largest US state

Most Americans know which state is the largest by area. But outside the US, some get this fact wrong!

Many people answer "Texas" when asked which is the largest of the 50 states. But in reality, Alaska is far bigger, covering about 665,300 square miles compared to Texas's 268,600. This misconception may stem from Texas's reputation as a "large state" or from the way many maps distort Alaska's true size, making it appear much smaller than it actually is.

Florida's capital

Miami is not only the most densely populated city in Florida but also one of its most famous, right up there with Orlando! Perhaps that's why many people mistakenly believe Miami is the capital city of the Sunshine State. However, the capital city of Florida is actually Tallahassee, which is smaller and doesn't quite receive as much attention.

The longest river

Measuring the actual length of a river can be tough due to the serpentine shape that these bodies of water often take. This may be why many people are unsure about which river holds the title of the longest in the US.

Well, here's the truth: At 2,341 miles, the Missouri River is the longest river in the US, though just by a small margin. In second place is the Mississippi River, which stretches for some 2,320 miles and is often mistakenly thought to be the longest due to that small difference.

New York's capital

Similar to Florida, New York State's capital city is not its largest or most famous.

Contrary to what many people think, the capital of New York is not NYC, but Albany. Although Albany is smaller than NYC, it's an important economic and political hub, and it was chosen as the state capital because of its central location along the Hudson River.

Large population

The United States is known for having a large population, partly due to the large size of its territory. But did you know it's also one of the most populated countries in the world? In fact, it's the 3rd most populated, coming right after India and China! There sure are a lot of us, aren't there?

Cypress Gardens (Winter Haven, Florida)

Long before the Disney parks arrived in Florida, another attraction was the most popular, drawing visitors from across the country.

It was Cypress Gardens in Winter Haven, Florida, which opened in 1936 as a botanical garden showcasing the state’s natural beauty. Over time, it became even better known for its water ski shows, something many Americans still remember from family trips in the 60s and 70s. But by the late 70s, things began to shift. The rise of the Disney parks changed tourism expectations, and Cypress Gardens slowly lost its spotlight, ultimately closing in September 2009. But it's not all bad news; parts of the original gardens still survive today, preserved inside LEGOLAND Florida.

New York State Pavilion (New York)

At the 1964 New York World’s Fair in Queens, the United States unveiled a brave vision of the future: the New York State Pavilion.

With its "Tent of Tomorrow," three towering observation structures, and a giant map of New York on the ground, it drew crowds throughout 1964 with exhibitions, shows, and concerts. But when the fair closed in 1965, the future it represented started to fade. Without a long-term plan or funding, the pavilion declined, and by 1974**,** it was permanently closed due to structural issues. Today, its rusted towers still stand over Queens, NYC, alongside the empty concrete frame. However, restoration efforts have recently begun, hinting at a possible second life for this future that never was.

3

Six Flags New Orleans (New Orleans, Louisiana)

In the early 2000s, it was one of the most popular amusement parks in the region, but soon after, it was left underwater and abandoned.

We’re talking about Six Flags New Orleans, which opened in May 2000 as Jazzland Theme Park. In 2002, Six Flags took over, rebranding it and improving its roller coasters, rides, and water attractions. Its downfall wasn’t due to lack of visitors or investment; it was something far more powerful: in 2005, Hurricane Katrina flooded the park , causing irreversible damage, so it never reopened. Today, it still stands abandoned, with rusting rides and empty streets that are now a reminder of the storm. But it still gets some use: today, the now-haunting site has been transformed into a frequent filming location for movies, including Jurassic World (2015) and Dawn of the Planet of the Apes (2014).

Palisades Amusement Park (Bergen County, New Jersey)

For decades, especially between 1950 and 1970, it was a classic summer destination for families, but today, it’s completely gone.

Palisades Amusement Park opened in 1898 on the cliffs of the Hudson River in New Jersey. And what began as a trolley stop became one of America’s most famous amusement parks, known for its roller coasters, neon lights, and a massive saltwater pool once called "the largest in the world." However, by the 1960s, overcrowding, rising costs, and local pressure pushed it into decline, and it closed permanently on September 12, 1971. Today, high-rise apartments stand where the rides once were.

5

Disney's River Country (Lake Buena Vista, Florida)

Have you heard about Disney’s abandoned park? Disney's River Country opened in 1976 in Lake Buena Vista, Florida, inspired by the vibes of classic American summer vacations. It had a rustic atmosphere, with wooden slides, rope swings, and water drawn directly from the nearby lake. It was a total success in the 1980s, but by the late 1990s, things began to change.

Newer water parks with advanced systems and stricter safety standards made River Country feel outdated, and Disney gradually shifted its attention elsewhere. The park closed "temporarily" in 2001, but it never reopened. Today, it still sits in the same place, partially reclaimed by nature, quietly overshadowed by the modern resorts around it.

Grossinger’s Catskill Resort Hotel (Liberty, New York)

What was once one of the most popular family resorts in the country is now an extensive, decaying space with peeling wallpaper and collapsing floors.

Grossinger’s Resort Hotel began in the 1910s as a small guesthouse in the Catskill Mountains of Liberty, New York. What started modestly soon grew into one of the region’s most famous destinations, reaching its peak in the 1950s and 1960s with a golf course and both indoor and outdoor pools. It was incredibly popular with urban and suburban families in the tri-state area, and it even inspired the fictional "Kellerman's Mountain Resort" from Dirty Dancing (1987).

But in the late 1960s, American vacation habits began to change. Air travel and cruise vacations attracted families, and younger generations no longer returned to the places their parents had once loved. The resort gradually declined, leading to its permanent closure in 1986.

7

Dogpatch USA (Marble Falls, Arkansas)

Dogpatch USA opened in the Ozarks of Marble Falls, Arkansas, in 1968, taking its name from the fictional town in the popular comic strip Li’l Abner by Al Capp.

Rustic buildings, rides, fishing ponds, and a small amusement area brought the comic world to life. It first attracted curiosity from local visitors, but never reached the popularity its creators had hoped for. Almost from the start, it struggled, in part due to its remote Ozarks location, which made it difficult for most tourists to reach, and its operating costs that surpassed attendance. Over time, the park gradually declined, changing ownership and shrinking in activity, before finally disappearing in the mid-1980s.

8

Ghost Town in the Sky (Maggie Valley, North Carolina)

A Wild West–themed amusement park sitting above the clouds in the Smoky Mountains sounds too good to be true, right? But it was real.

Ghost Town in the Sky opened on May 1, 1961, in Maggie Valley, North Carolina, at the top of Buck Mountain. Visitors rode a chairlift up to a full Old West town with saloons, staged gunfights, and mountain views. For its first two decades, it attracted steady crowds, but by the 1990s, it began to shrink. Rising maintenance costs, difficult access, and unstable ownership pushed it into decline. By the 2000s, the aging infrastructure became unreliable, leading to its first closure in 2002 and final closure in 2009. Today, the park still sits abandoned on the mountain.

9

Geauga Lake (Aurora, Ohio)

In the early 20th century, many Midwestern families had a go-to summer destination: Geauga Lake Park.

Geauga Lake opened in 1887 in Aurora, Ohio, as a simple lakeside resort. By the 1920s, it had grown into a full amusement park with rides, games, and roller coasters –like its classic wooden coaster, the Big Dipper– attracting thousands of visitors each year. Throughout much of the 20th century, it was a must-stop on family road trips. It reached its peak in the 1990s, after major expansions turned it into a large regional attraction, but those same upgrades also drove up costs and complexity. In the end, the expansion that improved it also sealed its fate, leading to its final closure in 2007.

10

Heritage USA (Fort Mill, South Carolina)

Sometimes called "Christian Disneyland," Heritage USA opened in 1978 in Fort Mill, South Carolina, founded by famous televangelists Jim and Tammy Bakker with the idea of building a major Christian-themed resort to rival the big amusement parks.

For a time, it was hugely popular, at one point even ranking as the third most-visited theme park in the U.S., with rides, a water park, hotels, and a large church auditorium. But in 1987, a financial scandal involving Jim Bakker shook public trust, and in 1989, Hurricane Hugo caused further damage. By the end of 1989, the park had effectively shut down, leaving its once-famous 21-story hotel as a hollow reminder of what it had been.

Harriet Tubman secretly worked as a Union spy

Most Americans know Harriet Tubman for her leadership of the Underground Railroad, but during the Civil War, she also became a Union scout and spy in South Carolina. Working with Colonel James Montgomery, Tubman gathered intelligence from enslaved people living behind Confederate lines near the Combahee River .

In June 1863, Tubman helped lead the Combahee River Raid, guiding Union gunboats through Confederate waters filled with hidden mines. The operation freed more than 700 enslaved people and made Tubman the first woman known to lead a major U.S. military mission.

2

Julia Child worked for the U.S. intelligence agency

Before becoming television’s most famous chef, Julia Child joined the Office of Strategic Services, or OSS, in 1942 during World War II. The OSS later evolved into the CIA. Too tall to enlist in the Women’s Army Corps, Child instead classified files and overseas communications in Asia.

One of her strangest assignments involved helping researchers develop shark repellent for Navy explosives and emergency rescue kits . The repellent used copper acetate and black dye to create an odor similar to a dead shark.

3

Benjamin Franklin conducted unofficial spy work in Europe

Benjamin Franklin was more than a scientist and Founding Father. During the American Revolution, he quietly acted as an intelligence organizer while serving as ambassador to France beginning in 1776 . Franklin cultivated secret alliances, intercepted information, and used coded correspondence to support the colonies’ fight against Britain.

Operating from Paris, Franklin built relationships with French officials and helped persuade France to support the American cause with money, troops, and naval power. Historians consider his diplomatic intelligence efforts essential to the American victory at Yorktown in 1781 and eventual independence.

4

Louisa May Alcott published thrillers under another name

Louisa May Alcott became a literary icon after publishing Little Women in 1868, but few readers knew that she had already written sensational thrillers under the pen name "A.M. Barnard." These stories featured revenge, hidden identities, forbidden romance, and dramatic crime plots that shocked Victorian audiences.

Alcott used a pseudonym because publishers often expected women writers to produce respectable domestic fiction. Many of her darker stories remained forgotten until scholars rediscovered them in the 1940s. Today, titles like Behind a Mask reveal a far more rebellious side of the beloved author.

5

Maya Angelou worked as San Francisco’s first black female cable car conductor

Long before becoming a celebrated poet and author, Maya Angelou made history in San Francisco during the 1940s. At only 16 years old, she applied repeatedly for a conductor job on the city’s cable cars after seeing an advertisement that excluded Black applicants .

Angelou refused to give up despite repeated rejection. She eventually became San Francisco’s first Black female cable car conductor in 1944. Years later, she described proudly wearing the blue uniform while working long shifts across the city before launching her writing and civil rights careers.

6

Dr. Seuss created classified wartime propaganda films

Before writing Green Eggs and Ham and The Cat in the Hat , Theodor Geisel, better known as Dr. Seuss, worked on wartime propaganda during World War II. Between 1943 and 1945, he joined director Frank Capra’s Signal Corps unit to produce military training films for American soldiers .

Geisel also drew political cartoons supporting the Allied war effort and criticizing fascism. Some of his films were classified during the war because they contained military training material. His animated work helped explain battlefield strategy and morale issues to thousands of U.S. troops overseas.

7

Babe Ruth once played an entire game with a fever over 102 degrees

In 1925, Babe Ruth became seriously ill during spring training and collapsed while traveling by train . Newspapers nicknamed the incident "the bellyache heard around the world." Reports from the time described Ruth suffering from a fever above 102 degrees while still insisting on returning to baseball activities.

Despite his condition, Ruth’s determination became part of baseball legend. The illness hurt his performance during the 1925 season, when the New York Yankees finished seventh in the American League. Even so, Ruth rebounded quickly and helped lead the Yankees to championships in later years.

8

Harry Houdini worked with police departments

Harry Houdini’s famous escape acts fascinated police departments across America and Europe in the early 1900s. Officers regularly challenged him to escape from handcuffs, prison wagons, and locked jail cells. Houdini often invited local police to inspect restraints before his performances began.

Beyond entertainment, Houdini also worked closely with law enforcement to expose fraudulent mediums and fake spiritualists during the 1920s . Using his knowledge of locks, hidden compartments, and deception, he publicly demonstrated how many supposed supernatural tricks were actually carefully staged illusions.

9

Frank Lloyd Wright hid a private apartment inside one of his buildings

Architect Frank Lloyd Wright secretly maintained a private apartment inside his famous Oak Park Studio near Chicago, Illinois. Built in the 1890s, the studio served as both his workplace and personal retreat while he designed many of his early Prairie-style homes across the Midwest.

The hidden living quarters allowed Wright to work late into the night and host select guests away from public attention. The building itself became one of the most important centers of American architecture, producing groundbreaking residential designs that influenced modern architecture around the world.

Muhammad Ali quietly funded humanitarian causes for years

Muhammad Ali’s boxing fame often overshadowed his enormous charitable work. For decades, Ali quietly donated money to hospitals, food programs, children’s charities, and international humanitarian efforts . Friends and family later revealed that many of his contributions were intentionally kept private.

In 1990, Ali traveled to Iraq during tensions leading up to the Gulf War and helped secure the release of 15 American hostages. He also supported global relief organizations and Parkinson’s disease research after his own diagnosis. In 2005, President George W. Bush awarded Ali the Presidential Medal of Freedom.
