Sorry, I just got back to this thread.
Really, I don't mean to knock ATL (damning by faint praise?), but Chicago, NYC, LA (yes Los Angeles), San Diego, San Francisco, Seattle, Washington D.C. all strike me as places that have more character than Atlanta.
I've been to Atlanta. I've been to the airport, Buckhead, Midtown, Underground, Downtown, Stone Mountain. I'm not knocking it as a nice place to live, but to me it doesn't have it's own defining character. It doesn't have "charm".
It's just another big Sunbelt city with nice tall glass skyscrapers. It just happens to have a few more hills than Dallas or Houston. Charlotte seems to be well on its way to "charm extinction" also. Yes, it's a business town, and more power to them. Maybe that IS it's defining characteristic!
