Well within your range, and south, would be Renfro Valley, KY. We stopped for a few days earlier this month. Hillbilly, gospel and Bluegrass capital of the world. Many music shows and a neat town in Berea, 12 miles north. Loads of galleries and artist shops. And a candle factory with an outlet store. We found a campground we liked in Berea ($23 for full hookups and Wi-Fi) and will clearly go back. If that sort of music is your cup of tea, it's well done. Also has the KY music hall of fame on the property.
