yes and no. Can someone who drives to the top of a mountain say they've climbed it? Where do you draw the line? IMHO, the slog up the ski area is part of the climb. However, I've already done it enough times that if the opportunity came to ride the snowcat or chairlift up, I may take it. I've already done my time, I don't feel the need to continue to do it every time I climb the mountain.
I agree that there are probably many people who take the snowcat that wouldn't make it up otherwise, and perhaps these people shouldn't claim to have climbed the mountain, maybe not even be on the mountain at all. If they can't make the easy part, why should they be on the hard part?
Seeing as how they probably won't stop the snowcat, I think they should just run the chairlift starting at midnight. Much quieter, doesn't have that aweful smell, and doesn't kill your nightvision. Then all the gumbies can use it and say they climbed the mountain. The rest of us can use it to skip the boring part.
