Our top reasons-from giant mazes to outdoor churches to the world's largest ball of twine-to pull off the side of the road and visit a while
Hawaii
The World's Largest Maze
The two-acre garden maze at the Dole Plantation in Oahu was recognized in 2001 by the Guinness Book of World Records as the world's biggest. The hibiscus hedges are seven feet high, and at its center the maze resembles a giant pineapple. There are guides to help those who get lost. 64-1550 Kamehameha Hwy., 808/621-8408, dole-plantation.com, $5, kids $3.
Idaho
Idaho Potato Expo
Off I-15, 25 miles southwest of Idaho Falls, is the Idaho Potato Expo, a museum filled with a two-foot Pringle (the world's largest), potato hand lotion, and even a spud signed by grammatically challenged former vice president--and good sport--Dan Quayle. Bonus: Each pair of visitors gets a free box of dehydrated hash browns. 130 Northwest Main St., Blackfoot, 208/ 785-2517, potatoexpo.com, $3, seniors $2.50, kids $1.
Montana
Lincoln's World Famous 10,000 Silver $ Bar and Casino
Actually, it's more like the 43,000-and-Counting Silver $ Bar and Casino: In 1952, Rex Lincoln cut a round hole in his bar, pounded in a silver dollar, and inscribed his name below it. Patrons have wanted in on the fun ever since. Each year visitors to this I-90 landmark, halfway between Missoula, Mont., and Spokane, Wash., donate nearly 1,500 coins to be mounted on the walls. Bring your own or buy one at the bar, then come back next year: Coins are mounted in January. Exit 16, Haugan, 406/678-4242.
Nevada
Little Ale Inn
Along Highway 375--better known as the Extraterrestrial Highway--this restaurant/bar/gift shop/motel is the only trace of civilization outside the ultrasecretive Area 51, just south of Rachel. Owner Pat Travis will be happy to entertain you with stories of actual alien sightings ("They came in the form of humans..."). Browse the aprons and tote bags in the gift shop, and order Travis's famous Alien Burger. "It's out of this world," she says. 775/729-2515, aleinn.com, burger $3.75. Alien salt and pepper shakers: $8.99.
Oregon
The House of Mystery and the Oregon Vortex
Self-described as "an area of naturally occurring visual and perceptual phenomena," the Oregon Vortex, near Gold Hill, in southwestern Oregon, has been defying the laws of physics since 1930. Balls roll uphill, brooms stand on end, and the mass of objects--including people--has been known to mysteriously change. Bring a camera. 4303 Sardine Creek Rd., 541/855-1543, oregonvortex.com, $8, seniors $7, kids 6-11 $6.
Utah
Hole N' the Rock
Forty-thousand visitors come annually to see this 5,000-square-foot house carved from a huge sandstone rock 12 miles south of Moab. It has 14 rooms, including an art studio and lapidary, where cocreator Albert Christensen once polished his rocks. All that's missing: Fred, Wilma, and Pebbles. 11037 S. Hwy. 191, 877/686-2250, moab-utah.com/holeintherock, $4.25, kids $2.25.
Washington
World Famous Bob's Java Jive
This Tacoma dive, where bands play nightly, has a jungle-theme interior--and it once featured live, swinging monkeys. Even stranger, it's shaped like a giant coffeepot: Built in 1927 as a coffee shop, it was once surrounded by other buildings that imitated their purposes (such as a gas station shaped like a pump). It's the only one left. 2102 S. Tacoma Way, 253/475-9843, bipolaraudio.com/bobs_java_jive.html.
Wyoming
The Douglas Jackalope
The town of Douglas--130 miles north of Cheyenne--is absolutely devoted to the rare jackalope, a cross between a rabbit and an antelope. Self-proclaimed as the Home of the Jackalope, Douglas erected an eight-foot statue in what's known as Jackalope Square. To solidify its place in jackalope lore, the town had hoped to build another statue (this one 80 feet tall and made of fiberglass), but the plans fell through. Jackalope hunting licenses are available, but no one has ever bagged one of the wily creatures. Douglas Chamber of Commerce, 307/358-2950, jackalope.org, free.
