I've been to the Vet and the Linc for Cowboys @ Eagles games and have lived to tell about it, so here's 2 tips for you:
1. Don't take anything anyone says to you too seriously. (they'll be drunk and loud, and you should just smile and let your team talk for you)
2. DO NOT GO TO THE BATHROOM BY YOURSELF! (made this mistake 2 years ago just after Halftime as we were blowing them out in front of their fans at the Linc........surrounded by cement and porcelain and pissed off Eagles fans, wearing a Marion Barber jersey = sticky situation. How'd I get out? See tip #1
)
Funniest part of that night was when the Eagles fans heavily booed their firework guy for setting some off after they kicked a meaningless fieldgoal when the game was way out of reach. :laugh2:
Have fun, good luck, and have a cheesesteak for me.
