I wouldn't even worry about humidity, at least if Georgia is like Alabama (Shoals area). I lived there 3 years, and fell in love with the area, and the weather. I thought I'd die of the humidity after hearing a lot of people talk about it, but I guess I just got used to it, or it wasn't that bad to me. Maybe just my chemistry. I love the South, and if it wasn't so far from what family I do want to be within driving distance of, I would go back there in a minute
I think I'd go for the places that aren't so advertised, find your own, special place, unless you want to be in the Senior Fast-lane, LOL!! Yeehaw!! Pappy and a few others here can tell you about Florida

They love it!
