I'm a Georgia Tech fan as well as a Tennessee Fan. The worst stadium I've been to(mostly for NO atmosphere) is Grant Field-Bobby Dodd Stadium. I say that as someone who has followed GT as well as Tennessee since I was a Kid.
the rose bowl sucks elephant di**. the parking situation is awful, the seats aren't comfortable, and you feel far away from the game.
the coliseum is cool b/c of the tradition, but remove that and it's also a dump
