On my rare visits to Atlanta from our dirt road in Alabama, we'd marvel at the speeds being traveled. It's possible we just hit it on a good day. I'd be doing 70 and folks were passing me like I was parked on the side of the road. Even my children quieted down without having to be told.
It's hard to be noisy when you are softly sobbing in terror.
Coming into or out of Atlanta on I-75, 80 mph is the slow lane.
