I looked at the Atlanta sites to see what there is. Here's what I found a few things:
Fernbank Museum of Natural History on 767 Clifton Rd, Atlanta, GA 30307 (404-929-6300) cross street is Ponce de Leon Ave. Sort of downtown-ish. They have dinosaurs!
Chateau Elan, a winery, off of I-85, is 45min north or Atlanta. $5 tour; $5 wine tasting; $90 for 50min massage. They also have a beautiful inn. I ck'd the price...$367 - $199 for 1 person for 1 night.

Too much for me at the moment.... Address is 100 Rue Charlemagne, Baselton, GA 30517 (1-800-233-WINE)
At or around Stone Mtn, back in the mid 80's, I remember going to an
antique car museum. I tried but cannot find it. Does anyone know about it or have interest in it? I'd like to know if its still around/where.
And, I'm another of those who can't do lots of hiking or stay out in heat due to health problems.
