They have track days at Nashville Superspeedway also at Barber Motorsports Park in Birmingham, AL and also at Talledega GP in Talledega, AL. Those are the closest. Tally is where more of them are at. That track is being redone this winter due to a highway project there. Should make for an interesting track.
There is a group hoping to turn part of the old DoE K-25 weapons facility in Oak Ridge, TN into a roadracing facility by 2009. Hopefully that works out.
