I live in a dorm on college too. Just bring alot of cigs with if you see a cop coming just roll the windows down and start a puffing the baccy like mad.
Just gotta be smart I mean if a cop sees a parked car with smoke rolling and nobody taking a cig to their mouth they are going to wonder what is going on. Always be aware of your surroundings.
I always do and everything has been A-Okay!!
