it all depends on the fraternity that you join. find the right group of guys, and your college years will be wonderful. i was in a frarternity, and it was great. every campus has greeks that are d-bags, nerds, drinkers, rich kids and so forth, the one i was in had everything from farmers to vietnamese we were a diverse bunch, but we had a blast.

find the right one and you wont regret it, but if you dont find the right group of guys, dont do it. and don't let them sweet talk you, dont rush into one, hang out with them for at the very least a semester.
