I adore Chattanooga, and it seems like a good central location, although it's a bit far for our more southerly members. Atlanta would be good too, but I hate that traffic with a passion.
I don't know the specific location of many CP sites, but I know a bit of other nature related stuff to do in the area. As mentioned before, there's the Tennessee Aquarium and Atlanta Botanical Gardens; here's some more stuff that I've thought of for get togethers and visits:
Tigers for Tomorrow- Attalla, AL
Georgia Aquarium- Atlanta, GA
Chattahoochee Nature Reserve- Roswell, GA
Chattahoochee National Forest- Fannin, GA
Birmingham Botanical Gardens- Birmingham, AL
Please add to this list if you can, and tell me which of these places sound most interesting.
I'm in Huntsville, AL, by the way.
