Holy heck they do have heavy traffic. My question is do they ever not have heavy traffic?
I go to Atlanta at least once a month, and have been for four years. I have a theory. Nobody in Atlanta actually has a home. They drive 24 hours a day. They stop for gas and food, and then start driving the interstate around the city again.
No matter what hour of the day or night I drive there, it's always nuts. I asked someone about the traffic, and he said, "well, Atlanta has three different interstates (85, 75 and 20) coming together)". Chicago has seven converging on the city, and Chicago traffic isn't as bad as Atlanta's. And Atlanta's pavement is much, much better than Chicago's, and doesn't have the constant construction.
