Found myself in Louisville Kentucky where I found a 4x4 Challenge which consisted of 5 burgers with 4 patties and 4 cheese slices along with lettuce tomato, onions and pickles. I picked a different cheese for each sandwich. I had 1 hour to eat or I owed him $49.99 plus tax and my pride. If you win you get the meal for free, a shirt or a hat. SPOLIER These burgers are freakin' delicious.
