The arena staff cracked me up. When I first got there, a guy looked in my purse long enough to see a tampon, then let me get in line. At first, they were saying anyone who left the line for any reason would have to go to the back--no bathroom, no little walks to stretch, nothing. They were escorting people to the bathroom in groups of four. It was like they were scared we were all going to go nuts and destroy the entire building, so they were being ridiculously strict. By the end of the day, they realized we were harmless and let us move around. I got a camera in but decided to just enjoy the show and not worry about taking pictures.
Security inside was very good. The security guard near me was really nice, but he did his job well, too. Someone passed out and had to be carried out, and someone apparently got hurt in the ellipse during Pride (I didn't see what happened--only the commotion after it). They also broke up a few scuffles before anything got out of hand.
