My husband and I have decided to do a road trip from Philadelphia to Nashville. Our inspiration for the trip is History Channel's American Pickers. We are definitely going to visit the Antique Archaeology shop in Nashville. We plan on spending 3 days in Nashville but we are looking for some off the beaten path or out of the ordinary things to see & do. We do plan on hitting the honky tonks & BBQ spots but we would like to do something at least a little different for 1 of the days. Any suggestions on short drives or day trips from Nashville w/some fun or interesting things to do? Thanks!
