First off, CONGRATULATIONS!  You got admitted to a very fine school.
Looks like others beat me to it, but hit the OSU Ski Team up!
We have people going up to MRM every day, you can easily hitch a ride.  And I mean literally pretty much any day someone is skiing.
AVOID the Ski Club, they on one trip a year for a week and have socials once a week at some bar.  We ski every week and party every week.
