well; my curiosity got the best of me, so I looked up ski patrol.
Most of what I found was volunteer duty, consisting of out-of-pocket registering, books, training, uniforms, dues, equipment, medical packs, etc. No income for them, just lots of expense and training. Didn't find much on those who actually get paid. But looks like the pay is not relevant in this type of work.
That'd be like a man who's so eager to cut firewood, goes out and buys some new saws, woodsplitter, axes, and accessories, hardhats, few pairs of chaps, 1st aid kits, a new truck , trailer, and log loader, and gives the wood away free.
