My son attended the HF camp. I agree with 089 - very well run and very well worth the money. There were 25 colleges represented, all of them higher-tier academic schools.
My son is an 09, so the fruits of the showcase, if any, won't be known to us for some time. But the coaches there were very accessible, very involved, and clearly serious about identifying prospects.
Can't ask for anything more. We will definitely do the showcase next year as well.
He was on the wait list for the Stanford camp, and so we did not go to that one. Next year if he gets into Stanford, I am not sure if we will do it or the HF or both.
Highly recommend the HF showcase.
