Where to go in north Georgia, Alabama and southern Tennessee?

My local rock and mineral shop has a map that I think comes from Gemstone Press www.gemstonepress.com it lists 7 or 8 locations in Georgia. You also might look at www.mamasminerals.com they have books, tools, equipment for mineral hunting and rockhounding. I just got a gem and mineral guide for the north west, I'm sure they have something for the south.
