I'm there as a freshman currently. I know there's a paintball club, so I'm going to ask those guys first, but other than that you'd just have to find individuals who are in the sport. I'm going to the rec sports expo on Sunday so I'll see if I can find any airsoft related groups (though I doubt I'll find any). I could start one I suppose, but schools aren't typically too hot on the idea of a club involving realistic replica firearms.
