Hi, i am in Marietta GA, and also agree that Diver Supply is a good shot. I have also frequent "the dive shop" in marietta as well. thats where i got all my gear. One of the best places around i have heard is the florida springs. i am trying go now for a weekend. Also i was just at Pelham AL, 2 hours away but a nice weekend spot that is not a lake. let me know if you want to dive sometime, i am always up for it.
