Make friends with other musicians. If you have a group of people who want to play bad enough, you'll be able to find a place to play. Opportunities do arise if you work hard enough.
I don't think OSU has made any accommodations for the normal musician on campus. They'd probably make a decent amount of money by building and supplying a recreational practice space.
I can never practice. I'm terrified of losing my skills after going months without playing ... before I came (to Ohio State), drums and music were my life.
