I'm going on a spur-of-the-moment mini-road trip with some pals to Nashville. Starting in Cincinnati, OH, we'll have about 3 days to get there. If anyone has any advice or tips about interesting back roads, cool spots that are not too far out of the way, lakes or rivers that we could check out along the way, kitschy flea markets, etc. I would really appreciate it! The itinerary is pretty loose so and we have plenty of time to veer off our route; but my car is pretty old so I don't want to push it TOO far, ya know?
Any advice would really help! Thanks
