Interesting place. Downtown is stagnant, not unusual for most US cities. All major action is in the suburbs, and a lot of people almost never go into town and never, ever, ever take the MARTA subway or bus.
Drove a rental from Atlanta Airport into Buckhead, the heart of the action. The major highways are big, pothole free concrete roads, for the most part well designed. Had an easy time for the most part driving through Interestates 75 and 85, which go right through downtown and Turner Field, of the Atlanta Braves on the way to the suburban promised land.
Atlanta Airport is a big, pleasant, well-oiled machine. It may be the best American airport. Like a hot knife through butter, you get to your flight and make your connection. Thats all I ask.
