I don't know what you're driving or what your experience level is so it is hard to offer advice. I will be out there tomorrow with a Liberty and a TJ. Uwharrie is probably pretty dry, so it won't be at its most challenging. Here's my general suggestions.
Don't go it alone, if you a lone vehicle, ask a group if you can tag along, likely they will say yes.
Air down to about 20 PSI. If you have AT tires you will be especially glad that you did.
Get off the trail when there are other vehicles coming at you.
Enjoy yourself! I will be on CB channel 4 and FRS channel 1 if you want to holler for help.
