Oh, and those who say that ski bums live in poverty, sharing rooms in shitty houses and all that other shit either haven't actually been a ski bum, or they've got the wrong attack plan.  I've lived in very nice living situations with enough money to do what I want, buy what I want, eat out a lot, and drink and party more than I should...
Working as a lifty or instructor is Ok, but it is very, very far from the ideal spot to put yourself in if you want to be a ski bum. Patrol is a pretty sweet gig if you have to work on the mountain.  Myself, I work my ass off all summer banking coin so I can live a comfortable lifestyle and be unemployed all winter with no agenda but skiing.  That being said, I choose to stay away from the 'Whistler's' of the world so I can afford to do such things.
