We weren't allowed anywhere near the stadium!
The dancers were dropped off at a local college, then the Super Bowl folks hired buses to bus them to the stadium just for the show and then back. They didn't get to see any of the game either. My DD said it was cool, though, that they had a huge police escort on the road to the game.
She had an amazing time, though. They got to practice all week with Katy Perry and the other performers and, of course, the show was totally once-in-a lifetime.
