Ok here's a dumb question - you meet a co-ed at a bar - hit if off - but you can't take her back to you place (too far, roommates, girlfriend, whatever) - where do you take her? Try to go back to her dorm room? Best case scenario she lives off campus in her own apartment but you can't count on that...
Go for the BJ in the bushes? LOL.
