re: Attending the game Saturday, driving from Bham to ATL day of, two questions:

Sorry I forgot, most everything has been mentioned already though. You don't need to buy the reloadable breeze pass, you can just buy the round trip ticket. From tbe HH station you're on the blue line, very simple. Get on the train eastbound, you can get off at either vine city or the dome stop. After the game do the opposite. After the game though there are 2 lines (blue and green) going westbound, so make sure you get on blue going to Hamilton Holmes.
