I heard of some hikers in the Smokeis being rescued and charged a fee. They were in some deep snow after a big storm. They didn't ask for help. So I don't think they should be charged.
The Kim's simply got lost and their problem was exacerbated by some thoughtless vandals who tore down a sign. No charge
The guys on Mt Hood knew the risks associated with mountain climbing. It is one thing to put yourself at risk (and therefore your wife and kids) but altogether different from expecting rescuers to put their butts on the line for your thrill seeking ass. I am still wondering why we try to rescue folks that climb mountains.
Call me hard hearted. Make em pay. I don't think it is too difficult to figure out who should pay.
