you kids, seriously.  i ski as stoned as humanly possible, all the time.  on my normal ski day, were talkin, at least one, usually two on the way up, first thing is find a hut and roast another two or three.  ski for an hour or two, find another hut.  roast down, go back out and ski hard for another hour or so, and then roast a fat one on the way down the last run of the day, and then another one on the drive down.  its skiing, not brain surgery.
and yeah, the cold takes away the buzz if you just ripped A bowl, but by the time lunch rolls around and youre seven or eight of em into the day then you got a good strong buzz goin.  so much fun!
