jot,
i think that almost all applicants usually roll in around 8ish. you could hit up the office around 730 to see what's shaking.
if you want to check out some lectures in the morning (if you don't have interviews from 8-10), we are having a lecture on the events of the cardiac cycle as well as on the responses of the heart to injury. should be pretty good. both lectures have reputations for being, atleast, interesting.
i'll keep my eyes open for the sikh!!
