It was a different era for college partying, but I'be been to large, small, famous and not so famous college party scenes. Some would blow your mind. The best scenes were the ones that had their own ecosystem. You don't need a ton of bars or a glitzy downtown scene. You don't even need a spring weekend free for all, which continued existence is a miracle. It should have by all comparable measures been killed in the 80's. There are few places that tolerate that kind of open underage drinking. But, I digress.
If you have a bunch of young people in close proximity on a regular basis, you'll have a solid party scene.
Back in the day I road tripped to SEC, Big East, A10, Big Ten, and Ivy country as well as D3 backwaters and women's colleges you never heard of. School size doesn't matter. In fact, all those places including several UConn contingents eventually came to visit my own little backwater school because we held it down like that.
Proximity, compactness, accessibility, and a regular crowd of diverse genders is all you need. You can roll like we did back then fully out in the open or with a wink and nod. But, it can still be done. I've seen the YouTube videos, you guys do OK.
