well, when you think about it, skiing is purely an entertainment form. That is unless of course you're out there killing some moose, then you slid your boots into your leather bindings on your wooden skis, and slide down to your log cabin.
So being that so few truly need skiing in order to survive (face it, we all say we'd die without it, but truth be told, none of us would just drop and die because we aren't able to ski a sick pow line through some trees) it's an extreme luxury. When you also think of the costs of running hotels, shuttle buses, keeping local business open....it all adds up. It's great for us-we get to ski, and the communities get jobs, and skiers coming through. But for the environment....not so much.
