The Corn Palace

Covered entirely with thousands of bushels of corn, grasses, and grains, the Corn Palace in Mitchell--with turrets, onion domes, and minarets--is America's answer to the Kremlin. The exterior of the palace is refurbished annually during harvest time (August through September), but its interior features year-round corn murals depicting the history of Native Americans and the white man. 604 N. Main, 866/273-2676, cornpalace.org, free. Key chain: $2.50.

Wall Drug Store

They arrive to find much more: Now an attraction in its own right, the store boasts an 80-foot-tall brontosaurus, an art gallery displaying western art and artifacts, and strange mechanical people like Dr. Feelgood, who for 50¢ will tell you about the benefits of snake oil. 510 Main St., Wall, 605/279-2175, walldrug.com, free.
