TR and Grateful, Those are great points obviously! Many camps are ran purely for instructional purposes and fulfill that expectation very well. Obviously the folks that do that should earn something for their efforts.
I think people's frustrations come from the Prospect Campbs, because we (parents) look at those letters that say our son is a top prospect and they need to come to their camp and be seen. We start to have a fantasy of Junior being singled out and given offer on the spot. It's easy to allow yourself to feel your son has been mislead. What we (parents) often forget is that every good HS player may be a prospect to them.
