Hey David, I have found that if you want to hunt for coins and jewelry, go to any older church that has a yard large enough to spend some time in. Be sure to ask for permission first. Most folks will let you hunt if you ask. If you are into hunting for relics you could do some research on the towns close by to see if there was anything going on in the rev war. There was some Civil War activity in western North Carolina. Just takes a little research. Morganton North Carolina had a place called Camp Vance which was a training camp for Confederate soldiers. I'm sure you could find several other places. It just takes a little research and reading.
Good luck to you and remember,
Keep on diggin!!
