My son participated in Cary, NC this past August, attempting to make the 2016 17U development squad.
Our region was ran by a bunch of homers, but even with the bias towards a few kids, it was still a fun experience. The fields are immaculate, the area where the complex is located is beautiful and at the end of the day, the National Selection Committee got it right, at least in our region. One kid torched the place for three games going 10-12 with 2 triples, 4 doubles, 7 runs scored and maybe 8 stolen bases. Was glad to see that kid make the squad, well deserved. My recommendation would be to go at it with your eyes wide open. Even if you make it to Cary, they are only going to take 12 kids from the trials so the odds are long, but if your kid dreams of wearing USA across his chest and you can afford the multiple qualifiers and travel that goes with it, give it a shot.
