Most here are aware of Showball & Headfirst camps. If you are a lurker they are both "high academic" camps that feature D1, D2, & D3 coaches. The campers are generally higher academic kids (at least a 3.0 unweighted GPA with some rigor and also 26+ ACT or equivalent SAT) and the schools represented are generally schools that one would need at least those types of academic chops to get in...often MUCH higher grades and scores.
Both organizations have camps across the country (mostly east and some west coast) and you can see most schools and coaches that will attend their camps on the website. Both camps are for 2 days and generally have a showcase the day prior with 60 times, positional velo, BP/Tee velo, fielding reps, and live batting practice. Day 2 is generally one long game (12 innings) or two shorter games. I believe that snowball bats 5 hitters per inning and also starts at bats with 1-1 counts. There are opportunities to connect with most coaches in attendance and at the end of the camp a coach will give you an evaluation or some feedback on the kid.
