Replying to Advice for a prospective ski-bum in the states?

I'm heading over to the US next season.
With the finances being tight I will probably be working on a resort. Anyone got any recommendations?
I've been looking at Aspen, Kirkwood, Copper, Winter Park, Heavenly or Mammoth.

I understand some drug test, so I want to avoid those ones (ie. Aspen), mind you if anyone knows how much they actually enforce it I would be interested to know.

Speaking of intoxication, do any former/current ski-bums in the US know how limited a 20 year old will be when it comes to hitting the piss? I'm guessing it depends on location, but suggestions on laid-back hills would be apprectiated. I'm dreaming of a US version of Nelson BC...But with a park...I wonder if Copper might fit the bill?
