you are a proud father and a strong Texan... keep your business to yourself. Dont give them any ammo, none. Just remember a friendly drunk before the game can be a miserable bastard if they are on the wrong side of the scoreboard.
Just going from personal experience at games, this will be a bad one unless the Eagles win easily. Like sticky says, late start equals more boozed up idiots, the philly fans are eating up that disrespect card and are already kinda pissy about it... on top of being pissed they are philly fans to begin with. their team hasnt had much success in the last decade, they will be extra amped. everything about this game says stay home... but thats not our nature now is it?
be smart, be safe, and enjoy the hell out of the experience brother. tell B once again that we are so proud of them and what they have accomplished.
