I've always wanted to run one of those. My biggest problem is I don't have the time or connections to get such a job. You mentioned the winch-cats. At the mountain up here that I do most of my skiing at, they have several runs that are double black diamonds that I like to ski, but even standing at the top will test your ability with hights...and they groom them on occasion. Its so steep that not only do they winch the cat up, but then they turn around and lower it back down.
