For centuries, moonshine has loomed large in the American imagination — the illegally produced liquor was a key part of the underground economy of many states in the South and in Appalachia. During Prohibition, backwoods moonshiners helped supply speakeasies across the country. NASCAR has its roots in the souped-up cars used by moonshine runners to transport booze. Moonshiners have been the subject of dozens of movies, hundreds of songs, and numerous TV shows, from The Dukes of Hazzard to Moonshiners, a reality show on the Discovery Channel.
