As long as no one sees, you're set. UR is not the biggest watchdog; they allow students to act on their own and do not impose overly strict regulations for housing, visiting, and the like. There is not a maze of bureaucracy to deal with in administration, and if you do something wrong, it goes through a direct process of discipline. Students are left to their own devices, for the most part, except for fraternities. When it comes to cracking down on drinking at frat houses, there is an inordinate amount of attention given. Beyond the frat houses, you're out from under security's eye.
Little resentment exists between the student body and the authorities. Some fraternities are angry over their maltreatment, but most students do not have a problem or feel that their rights are been impinged upon. They are now even phasing in a non-smoking policy campus-wide for all the dorms, and students have not had an adverse reaction. If a reasonable rule is set in place, no one finds reason to rebel against or disregard it. Overall, people are mostly well behaved, and the school leaves well enough alone.
