I go to UW. You have two options for ski clubs:
Husky Winter Sports, which runs a ski school at Snoqualmie. You get a free pass, but you have to teach lessons and ski at Snoqualmie.
Husky Snowboard Team. This is basically just a big rideshare pool that pays for some gas money. They go to various places, including Stevens.
Both organizations do parties and a movie premiere, but HWS seems to party more. Or you can meet people. I'm lucky in that I have a car here and already know plenty of people in Seattle who ride Stevens, so I have no problem with carpooling.
