I have been into KJWN john tune and KBNA nashville. Tune is easier in and out, cheaper, offers self service fuel pumps, close to downtown, etc. Without looking, I seem to recall a nonstandard traffic pattern and runway numbers changed at some point if your database is old.
If you go into tune, expect to hear a local radio break through on CTAF when about 1-2 mile final. Also, look at the towers in the area; there are some very high towers relatively close to tune.
I have also flown into Tullahoma, TN as was mentioned. Tullahoma offered me a courtesy car and is only a few miles down the road from the Lynchburg, TN home of Jack Daniels brewery which is beautiful and offers tours. It would be one to consider. There is also a wood prop shop nearby Tullahoma, I do not remember their name, but they would come to the airport to pick up a prop if you dropped it off for overhaul and have it waiting at the airport on your return flight.
