I was Class of 2020 at SU. There were a handful of us park skiers at the school, but not a ton. I skied the Lab park a couple times and its pretty decent. Fun to just do hot laps through, but not so much like a hard shredding progression park. Mostly rails and a small jump or two when I was there. Couple short flat boxes and rails, some bigger boxes (cannon, battleship, etc) and a handful of decent rails (short dfd, the sketchiest rainbow rail I've ever hit, and some longer small flat tubes). Id say at it's best you could probably get 6 or 7 rail hits in per run. Don't let the state of the park totally dissuade you though because Lab is a really fun little community mountain, and that is a lot more what the ski scene at SU is about. Ski Club is pretty rowdy but really fun times and good people. It's just as much about the social aspect as it is the skiing aspect. I usually found myself just wanting to have a fun sesh with friends hot lapping more often than super hard shredding.
Of course, I haven't been to Lab since 2020 so I can't speak on post-COVID, but I'm sure not much has changed.
Theres a couple really nice urban rails around the SU campus area as well. HMU if you want some deets.
TLDR; SU is an awesome school and while I didn't ski park as much while there, I don't regret it at all. I'd try out Ski Team freshman year and if you don't like Lab, the send to Greek peak isn't bad.
