Fraternities: What % of your pledge class is "committed" before formal rush begins?

I am curious about the summer rush too... only a few of our guys are around during the summer, how do you rush people if nobody is there to meet them... are you on campus year round??? how do you meet the new students before school starts??? ours don't show up until they can move into the dorms, a week before fall classes.
