Michigan — Mount Nacheesmo
At Tio's in Ann Arbor, Mich., one hungry person has 45 minutes to consume this 5-pound mountain of nachos smothered in beef, pork, chicken, beans, sour cream, veggies and three different kinds of cheese. You can't leave the table after the challenge has started. If you finish the feast, the nachos are free. You also get a T-shirt and eternal glory on the Tio's wall of fame.
