I'd stay away from Uwharrie until you are both real comfortable with riding. The place is full of rocks, quads, jeeps, and Humvees. Off all the places I have ridden, this is the worst. Don't get me wrong, definitely fun when you can get away from the 4 wheeled vehicles, but that is hard to do on the weekends.
Agree on Andrews - not for beginners or trail bikes for that matter.
I think TNT has the best mix for beginning or returning riders. The kids track, intermediate track, flat track, and trails are a blast. Plenty of variety and definitely geared towards the family.
I think Brushy Mountain is next best, Brown a bit more advanced, and then Uwharrie as a last resort as mentioned earlier.
