Hey man, we're in the same boat. We're from Pittsburgh but will be in Miami for the game. We likely won't rent a car unless necessary and have heard that there aren't any bars/restaurants right next to the stadium. We're trying to find a Steelers tailgate party to join. We'll bring whatever we need to bring, as well. Like your wife, my girlfriend has never been to a Steelers game and I'd love to have her experience it with other Steeler fans. Please let me know if you hear of anything or if you want to join up somehow.
