I have lived around the country.
Metro Atlanta is big (about 6M people). 9th biggest market in the country. About the same size as Metro DC.
Traffic is terrible. I live 4.5 miles from work. On a bad afternoon, it sometimes can take me an hour to get home. Full disclosure: I drive through the worst traffic location in the city.
Lots to do.
Although we have all professional sports (except ice hockey; we can't keep a hockey team). Even the pro soccer team has a lot of support.
Lots of restaurants. Really good ones.
Lots of entertainment (including adult). Almost every major musical act has an Atlanta stop.
Plenty of bars, but not many old-time neighborhood bars.
Plenty of hot women.
Many transplants from the North.
Overall very conservative. (Newt Gingrich comes from an Atlanta suburb.) We have a stupid redneck governor. Several of the mayors have been crooked.
Lots of rich people (including billionaires). Plenty of luxury and exotic cars.
For the most part, people are friendly.
Big-time airport.
With exceptions, the weather is good. When it snows (which is rare), people go into panic mode.
We do not have big parks (as Louisville does), but lots of smaller ones.
We have a puny river if you want to do some water recreation. A few lakes nearby.
Lots of festivals. Great people watching.
Pretty much the capital of college football. The College Football Hall of Fame is here.
Atlanta has little regard for tradition. We build stadiums. 20 years later, we tear 'em down and build new ones.
We have lots of big sporting events here: Summer Olympics, this year's Final Four, Super Bowls, World Series, all-star games for NBA, MLB, bowl games, etc.
(FYI, I have always lived ITP.)
