As an afterthought: You will hear a lot of folks on this list talking about the "manual focus feel" of autofocus lenses. That's simply because sometimes AF isn't the answer, your example is one of those times. Manual focus would be the best solution. Prefocusing the lens at a spot where you expect a skier (or car, horse, etc)to appear and taking a shot at that point is a technique others and myself haved used with some success.
