As someone that lives there let me tell you there is no "downtown" Atlanta. There is a neighborhood called Downtown, but it's one of three (four, or maybe even five, depending on who you ask) major, dense business and retail districts in the city limits, and even more in the suburbs. And yeah, would take you about an hour to hit all of them. Probably more with traffic.

It's a very polycentric city. Kind of throws people off when they first come here.

and LOL at the guy saying "no one wants to live in Georgia." This is what happens when you don't ever leave the Bay.
