Not in blue ridge, but north ga basically has the same weather patterns which promote the same mast crops. Id be happy to provide you with tips on bears through private messages, but areas themselves are hidden like my tax returns. I work very very hard for bears. In the blue ridge area, your best bet for bears is cohutta for sure. Id look at topo maps and search for long, narrow, and flat ridges from 2600-3900 feet. Id look for ones that are a long way from the roads. My favorite bear places are usually 2-6 miles from the truck, have a thick enough understory for stalking but not too thick that you make a lot of noise while slipping. We do sit some on good trees but our main strategy is slip hunting and listening for bears up in trees. Sneak up and wait for them to climb down and shoot when they get close to the deck.
