Heh, I was an art major as well, and I loved my sorority! But I do get where art colleges are generally less inclined towards those sorts of things.
Not to discourage you, but this is going to be one heck of a battle. Something you could look into would be fraternal groups that exist outside of your college. You didn't mention where you are going to college, but you could investigate groups like Beta Sigma Phi (

I know this might not be exactly what you were looking for, but it is of course an option. Good luck with art school!
