maybe keep an eye on skicarpool.org...i've never used it (or talked to anyone who has, for that matter) but if you're looking to save some cash, this might be helpful.
also, if you know any kids in boulder, i'd definitely say take the RTD from dia to boulder for $11.50, then get a ride to summit from there, which would not be at all too difficult. i'd say you could crash on my couch for a night, but i live in a goddamn dorm. freshman year must end. now.
