Do you just need flavor wood for your smoker? If so (I see you are a fisherman, assuming so from your profile), there are all sorts of desirable flavoring woods growing wild in your area that you can gather from your boat along the Savannah River. Pecan, white and red oak, hickory, just to name a few. Commercially there is peach and pecan. And cherry is common as an ornamental.
If you cook with wood instead of charcoal, there are hoards of firewood sellers on Craigslist. Just go to the Augusta CL and search "fire wood". I think you'll be shocked at how many listings there are. And I'm sure there are some who know the difference between white and red oak, pecan and hickory.
