the elusive "party"

Combing through the forum, I have yet to find a post the adequately addresses the quality/quantity of frat/sorority/house parties. As a possible student and rusher this fall, I'd like to know the availability of and general attitude towards alcohol consumption at parties (if there is any). It isn't a deal-breaker if there isn't any, but as a man pursuing a full college experience, I would hope that it's at least remotely available. I'd appreciate a timely response.
Cheers!
