I have not read through all the posts, but as a coach, who also grew up going to camps at mt hood, I will say this - summer ski camps come in all shapes and sizes, just like kids who participate in race programs, and kids who play all sports. If your shocked by the lack of athleticism compared to high level youth soccer/baseball - possibly you should think about the comparison you are making. Also if you ask me, the best part about youth racing programs, is that they make an enormous impact on the skiing development of every kid, from the next ted ligety to future nastar gold medalists.
If you want to see the most athletic young ski racers, you need to be at the right camp. And the really athletic kids from 8-16 are in very specific programs. Not because their parents buy them into it, but because they do really well at big events over the winter and the sport get segmented very quickly. Particularly around age 14, the listed middle band of the group.
Example of this is as follows, I attended NASC, a camp that was hugely impactful for my skiing at the time and super fun. My memory is a bit foggy on this topic, but as I recall, the week before the camp formally opened all these rippers, like top 20 at eastern JOs would be out there training with the coaches and no random joeys. During the regular sessions there was a wide mix. (I was definitely one of the random joeys, but really benefited from skiing with the councelors who were generally noram level)
