I have very rarely seen a student section anywhere that DIDN'T have unusual and or douchey people in them.
To me, it looks like a bunch of college guys that are trying to ***** for camera time. And that's everywhere.
At Duke, it's the worst.
Probably wouldn't be crowd that I hung out with in college- check that, it wasn't the crowd that I hung out with in college- but to each his own, and I suspect it's like that across America, and not a MSU only "issue".
