Anyone skiing off piste when there's a major avalanche warning in place should not expect rescuers to come out and save them. Their families should pay for any recovery of a body. You were warned, you ignored it, you caused it, you pay for it.
@anon_opin That's fair.
I think you should have to pay for any wilderness rescue if you were a dumbass about it (improper gear, etc.) but I don't know how you could possibly enforce it.
