Kentucky

For the next leg of their journey, Bradley and Barney visit the Red River Gorge in Kentucky, before heading to the supposedly haunted Poasttown Elementary School in Middletown, Ohio. The next day, they travel to Louisville, birthplace of legendary boxer Muhammad Ali, where they follow in his footsteps by sparring at the local boxing gym. At the end of a long day, Barney rewards his dad with a well-earned meal at a KFC restaurant in Kentucky - the home state of the chain's founder Colonel Harland Sanders.
