Odd - Interesting - Bizzare - Strange

If you've ever gone on a road trip, chances are you've driven past a few unusual tourist attractions. And if you've stopped to take a look, you know they can range from odd to completely outrageous. Below, check out our list of 15 wacky ones worth seeing, including a museum devoted to toilet seat art and the world's largest hammock. Bizarre? Yes. But they're certainly a welcome change of scenery as well as a great excuse to pull over and stretch your legs.

In 1968, John Milkovisch, a retired upholsterer, began a very unique home improvement project; he started by inlaying marbles, rocks and metal pieces to replace the grass in his yard, then moved on to adding aluminum beer can siding to the exterior of his house. Now the home is completely encrusted in an estimated 50,000 beer cans and open to the public for viewing. Address: 222 Malone Street, Houston, Texas

A world of paranormal activity awaits you at the Oregon Vortex, a spherical field of force that temporarily suspends the laws of physics. What exactly does that mean? At this tourist destination—open to the public since 1930––you can see brooms standing on end, balls rolling uphill and people appearing shorter or taller than they actually are. Address: 4303 Sardine Creek L Fork Road, Gold Hill, Oregon

Off North Carolina's Route 158 sits a hammock suitable for any giant-sized napper. The 42-foot-long lounger is made from about 10,000 feet of rope and can support up to 8,000 pounds, making it perfect for kicking back en masse. Address: 8887 Caratoke Highway, Point Harbor, North Carolina

Artist Barney Smith, a retired plumber, has been named "The King of the Thrones" thanks to his very unusual canvases. Proving that plumbing can be an art, his passion is painting and decorating toilet seats, which he displays in his Texas garage.

On a wooden dock in a pond near Syracuse, New York, sits a teeny-tiny church. The pint-sized house of worship was built in 1989, and is just 3 feet by 6 feet and has only two seats. There are no regular services, but Cross Island Chapel is available for special occasions, like a 1990 wedding in which guests had to sit in boats outdoors. Address: Sconondoa Road, Oneida, New York

In 1897, a carpenter named Pearle Wait created America's favorite dessert in Le Roy, New York: J-E-L-L-O.

Built in 1934, this smaller version of the Leaning Tower of Pisa was erected by Robert Ilg to hide an unsightly water tower. Only half as tall (94 feet to Pisa's 177 feet) and half as leaning (7.4 feet off vertical versus the original's 15-foot lean), the monument was later donated to a nearby YMCA and includes a plaque at its base in honor of the famous scientist Galileo Galilei, of whom Ilg was a fan.Address: 6300 Touhy Avenue, Niles, Illinois

Most kids lose a pair of shoes in a tree due to a playmate's prank. But now, that child's play has been turned into interactive art at the Shoe Tree near Middlegate, Nevada. Already covered in more shoes than you can count, the tree's branches are draped with footwear from both tourists and locals alike. Address: Highway 50, Middlegate, Nevada
