I'm assuming/hoping that the ingenuity of students will mean that a lot of socialising takes place off-campus - no-one is going to be able to police a group of them sneaking off to the woods/park to drink cider in the evening, or going to a city centre pub or two.
Last week my family, kids and all, went to our local beauty spot to spot Comet Neowise. My husband is into star gazing and has been to this place often in the past to see meteor showers and other such, he says he's only ever met other star gazers there.
This time we stumbled into a teen party. You can imagine our confusion....a staid family, with little kids, dressed for sitting in the cold, walking right into a hippie party! We stood there blinking in confusion for a few seconds. Then a young girl handed me a glow stick and tried to lead my husband onto the woodland dance floor. I've never seen him that scared 
We beat a hasty retreat, wishing them well.
They all seemed like good kids, and weren't messing about. I popped there the next day and they'd obviously not littered the place.
To quote Jurassic Park, life will find a way.
