If I'm paying, I'm watching. Considering that the only job my kid currently has is "professional dog walker" for his Grandma and another elderly couple down the street, I think I'll continue to be counted on for money for a bit longer....
I'm going to suggest some different considerations. While it is the parents money which is usually paid, it is about the experience of the player, not the parent, in my opinion. With our son, although he did not attend Camps and showcases at anywhere near the numbers which can be involved now, the ones he attended were quite important for his exposure.
In our situation, the issue of the parent being at the Camp was a choice which involved our son and what he felt would be best for him to compete, without added pressure to perform. If asked, I would tend to suspect most of our son's will admit to feeling a sense of added pressure when they know they will be under the scrutiny of college coaches and recruiting.
I would tend to suspect most of our son's will also admit to a sense of some added expectations when they know their parents are watching and hopes or expectations for recruiting exist.
Clearly, I have what seems like a contrary position, but I don't think the answer comes from a group of parents on the HSBBW. I think it should involve our son and what he thinks would be best for his performance on a college campus in front of college coaches, especially if the Camp or showcase is one where some expectations for recruiting exist.
My thoughts would be very different for a college camp which is instructional.
