The irony of the recently-revamped Jack Daniel's Distillery being in a 'dry county' is lost on no one – local liquor laws dictate that no hard stuff can be sold within county lines, but they do give out small samples on their free hour-long tours. For $10 you can take a two-hour Distillery Tour (book in advance), where you'll get a more generous sample and a scenic tour of the countryside. This is the oldest registered distillery in the US; the folks at Jack Daniels have been dripping whiskey through layers of charcoal then aging it in oak barrels since 1866. It's located off Hwy 55 in tiny Lynchburg.
