We weren't allowed to leave campus, and we had to take seven classes all four years. You had to get an off campus permit to go to a doctor's appt and excrement, and they were hard to come by. Readmit forms to get into class the next day and show why you were absent were always sitting right behind the desk. We took a shitload of them every year. The guards made it really tough to get off campus, but we'd go smoke in my buddy's Vanagon or even freak chicks occasionally (separate times I. That one obviously). There were guards at each exit, but only one guy patrolling all three lots who we called Mario for his hair and mustache. I don't think he had any sense of smell because we never got caught.
Had another friend who stole alcohol constantly from the grocery store and sold it out of his trunk on campus to rich kids. Paid for him to restore his POS old Mustang.
