Georgia is probably sandy near the coast, at least that's how Virginia is. It's amazing how different things are within a single state (and not even a very big one!). I grew up on the edge of the Appalachian foothills, with heavy red clay and shale, and in zone six where we got at least a few significant snows each winter. Now I'm on the coast, with nearly pure sand, and in zone eight where frosts are infrequent. There's barely 200 miles between the two!
