Brian, if you're traveling thru Kentucky, I think Land between the lakes
http://www.kentuckylake.com/lbl.shtml has several campgrounds and they may only be a day drive from Nashville. DW and I stayed at one of the campgrounds several years ago, (can't remember which one, but it was nice.) we are also planning to be at Nashville shores. Looking forward to our first rally.
