Arkansas — Boss Hog Challenge
If you find yourself in Imboden, Ark., looking for an uphill caloric battle, no one has ever finished this truly insane food challenge. Pig-N-Out BBQ has a fearsome 5-pound burrito (or sandwich, if you so desire) filled with barbecued pork and covered with cheese and sauce. There's also a side of curly fries. If you finish it in 45 minutes with no bathroom breaks, it's free.
