Hello there. Well, I don't live in the area, I'm outside of Raleigh, but my father-in-law has about 22 acres of land over in Westfield, just a few minutes from Mt. Airy. Every time I go down I bring the detector. So far, on his land I've just gotten a bunch of old farm tools and misc items. I don't get down there very often anymore, maybe every 3 or 4 months.
Like nc-joe said, if you something lined up I'd be willing to hunt with you, assuming I can get away from the wife and kids.
There is enough history in that area that there should be some good finds. Maybe even a little gold!
