I go to a place in TN called Aetna Mtn. It's just west of Chattanooga, which would be close to a 2 hour drive for you, but it's a big place to ride. Lots of rigs up there nearly every weekend. Some mud, mostly rocks and hillclimbs though. We're actually planning a trip this weekend but will probably take 4wheelers. If you ever want to make the trip and try the place out just let me know and we can set something up.
Also I think Wheelin in the Country is just a peice up 65 North too. Never been there but I here it's a good place to wheel.
