none of these bother me so much, i wont let em ruin my good time, but i have noticed:
The Guardians - their sacred duty is to block all gates and trail merge zones, on special days they block the entries to lift lines. invariably they are skiers
The Placeholders - they choose to wait for their buddies between the scanner and the chair, pulling to the side a bit but not out of the damn way. and everyone is wondering wtf they are doing, if they are loading up or what. sadly, can be either skier or boarder
The Boardslappers aka Beavers...we've been over this
and my (least) favorite:
the Iphone Ass(sitting) Holes: these are boarders who have yet to learn how to strap in standing up, who string themselves in a line across the hill instead of stacking up, and think this is also the perfect time to check their twitter, facebook, or call mom and tell her about the view.
