My dad grew up in Savannah, my mom in coastal Georgia, and we lived on St. Simons.
I shouldn't have said that about the people, but I get a PNW vibe from you, and Georgians are not like that. It's hard to put into words. I could see you finding a crowd in say Athens, but I looked on a map and that is an hour and a half from the CDC. But I am guessing the CDC people are like that, and you would probably like them a lot, and they might have a wide social circle.
Georgians tend to be very down to earth, practical, and socially and politically conservative; often they are religious; they tend to be kind and friendly, but there is a mistrust of people coming in from up north and acting superior. And believe me, people from up north do that all the time.
They think it's good that they have reopened the state, for example, and probably don't agree with you on how to handle the virus. But then again, if he's working for the CDC, you can probably find many like minded people.
But the local society tends to divide itself by things like what church you went to, who your family is, etc. But I doubt you want to get in with those people anyway.
I think you'd like Athens.
All of my observations are based on things from growing up, and Atlanta is probably very different now, very open to outsiders. When I went there last time a couple of years ago, the traffic was so horrendous I would never live there. Growing up, it was known as Hot-Lanta, and that wasn't a compliment, and it wasn't about the weather--it was considered rowdy, dangerous, and a big drug scene.
It is also hotter than hell in the summer, with no breezes, and I can't breathe there. I once went on a bike trip with my cousins as a 15 year old and almost died of heat stroke.
Ugh.
Edited to add: You really have to go down there and see for yourself. And go in the summer, now, since you will be living there. Check it out; the state is open, and you will have motels and restaurants and be able to get the vibe for yourself. Then you can see what the summer is like and what the people are like.
