OK, I Googled and immediately came up with a chapter website afor my sorority there, which includes some info/contacts for recruitment. It's not hard.

At any rate, if I were you I wouldn't stress about it over the summer. UCSC is one of those schools where you can just sign up for recruitment when you get to campus in the fall.
