Start the ultimate American road trip with a cruise in a wild, psychedelic art-car in San Francisco, California. Then journey to a wacky culinary competition in Marlinton, West Virginia, where a heated roadkill cook-off is underway. Head north to gear up for an unusual race in Delaware, Ohio, where folks prepare for the annual Lawn Mower Race. Finally, set out for the shores of Delaware to the town of Millsboro, where residents blast pumpkins into the sky at the Punkin Chunkin' Festival.
