If you've never been here check it out. Brushy Mountain.
http://www.bmmspark.com/ Awesome place. Geared towards bikes very, little stuff that is quad accessible. Good single track & elevation changes. We had a blast there last January. It was rainy & cold but great riding. Beware of the young ladies in the concession trailer. Between that accent & those eyes....well, let's just say it was a good thing there were other divorced men there of stronger will. Could have been my fourth ring.
Gulp.
And this may be a bit closer to you. Carolina Adventure World.
http://www.carolinaadventureworld.net/ Not as much single track but a lot more diversity. Endurocross track, motocross track, etc. It was raining while we were here too. But the dirt was amazing.
I could spend days at either of these places.
