I got invited last year and this year. Went last year. It was a really a good time. Good coaching, and got to train with some cool guys.
was it worth the money? I'm not sure, I coerceded money out of my school to help me pay for it. I wasn't able to take full advantage of the camp (I was one month into racing at the time and was still even slower than I am now).
But KP, I would agree with a previous poster; If there is any chance you'll regret it later, then GO. Enjoy it and learn a lot. Particularly if the parents are paying.
