S1, E3: Only in America could you kick off your shoes and perfect your form in the Mud Pit Belly Flop Competition at the Summer Redneck Games in Dublin, Georgia. Or join the aliens of Roswell, New Mexico, for the annual Roswell UFO Festival, which celebrates the unknown with performances and costume contests. To the east, Black Rock, Nevada, hosts an amateur rocketry competition that threatens to blast out of this world. But if you can't build a rocket in your home, a cardboard boat will do just fine for the Cardboard Boat Race in Heber Springs, Arkansas.
