Vending on college campuses?

My uncle brought up this idea the other night and it keeps popping into my head. My first actual event is in August, but I can't wait that long to move some inventory, so I'm looking for alternative places to vend at! Has anyone ever heard of or actually done this before? There aren't many events coming up in my area, so again, I'm looking for alternatives. My line is centered around "good vibes" and just spreading happiness. It's been deemed popular among longboarders/skaters and video gamers alike. Any ideas would be fantastic!
