The biggest rival of my alma mater is Western Michigan. The difference between our game and other major rival games is EVERYONE gets together after the game and parties - CMU and Western fans alike. It's a friendly hated rival...no trashing of cars or fans, or anything like that. Usually you see brown and gold mixed in with the Maroon and Gold all over the stadium. This is mostly because so many CMU students have friends that attend Western.
Kinda stupid to beat up the car of your best friend even if they are a hated Bronco, ya know??? But then, maybe Colorado-ians (???) are stupid??!!!
Some stadiums, they are just jerks - and drunk jerks at that. I find it rediculous when people get offended when you're rooting for your team when it's their opponant. Everyone has the right to root for whatever team they want to root for - and if it's your opponent du jour, well, so be it. This happened to me a lot when I lived in Kansas City. I'm a Tigers fan (and Pistons, and Lions, and RedWings), and those stupid Royals fans were mad at me because I didn't root for the Royals! They actually believed that since I lived in Kansas City, I had to root for the local teams. Sheesh!!
I hate... I MEAN HATE notre dame (no caps on purpose as a sign of total disrespect). Their starting QB last Saturday is this great kid from Chicago who I met at a dinner a couple years ago. Now, I rooted for n.d. to lose, but rooted FOR Demetrius. But I would never trash the car of an n.d. fan...throw up on it, but never trash it. LOL!!
