Oh dear god I just got back from Atlanta. I don't see how on earth you can ride your bike there. And I'm talking about some of those places you listed as being good for riding, like Roswell and north perimeter places. Atlanta looks like a death trap to me. It's got to be the most car-centered place I've ever seen. I only saw 3 cyclists the whole weekend. One guy riding home on a Friday and two guys early Sunday morning before traffic got bad.
