Football is an outdoor sport made to be played in the cold rain & snow. Some of the greatest games where in bad weather including the ice bowl up in Green Bay. I'm sure they will be able to figure something out for the 10 minute half time show even if there is precip falling. As for the 2 weeks of entertainment before the game date. Well I'm sure the majority of that will be indoors across the metro NY area which has the most diverse amount of entertainment options available in the world. This Super Bowl needed to happen to stop becoming the same old game played indoors or in a town that has weather like a summer vacation where the excitement is going to the beach.
