Philadelphia is the only city that I'll never go to another game at. They could be hosting the Super Bowl for some reason and I wouldn't go the see the Cowboys win if I had free tickets for a luxury box.
Four years ago I went with 3 friends, one of whom was a Eagles fan. We were minding our own business walking through the parking lot when 6 guys jumped us. They were trying to even beat the Eagles fan simply for being our friend.
With two of us being former college wrestlers, one former college D-lineman, and one guy that could take the other three by himself, we were holding our own until four or five more people decided that it was a sin that we weren't being properly beaten.
Needless to say, security was nowhere to be found.
I hate the litigous nature of our society, but someone is going to have to sue the team and city for a serious injury before anything changes.
