At HF they not only have the coaches stand in front of the players on the first day (and wave to them as they are introduced) they also provide a booklet with all of the coaches in attendance with their picture. I saw many player/parent combos going over the book, looking for coaches and then going up to them to talk. As a few have pointed out, there were a few extensive threads on HF and Stanford not that long ago and many of us just had players attend one or both of them last year. Our 2016 only attended once in Aug but I'm happy to answer any HR related questions (if I can) via PM.
