Traffic crawls through downtown Atlanta along Interstate 75/85 during rush hour in Atlanta, Ga. - 

A quick final thought today -- literally on the way out the door to go back to the airport.

There's no logical reason for Atlanta to be where it is, y'know. There's no natural harbor or geographic feature that dictated 175 years ago that they put a city right here.

It was, to get back to Mayor Reed's point, infrastructure that did it. Railroads back in the early days when this city was called Terminus.

Ed Glaeser, the Harvard economist, says whatever Atlanta's economic problems right now -- it's a bad idea to bet against a concentration of smart ambitious people.
