No the Coast Guard do not charge for rescues. I had a conversation with a crusty old Coasty last year on this topic. He was outraged that we dont charge climbers on Rainier, and I asked him the question of Coast Guard rescues. To him it is somhow different?????? Not only are they more expensive, they are more often the case of total stupidity by the person getting rescued. I dont beleive for a second that we should be charging for Coast Guard rescues. Like wise we should not be charging for climbing rescues.
