Team California.
Echo everything 2019Dad wrote. Expect about 60 colleges there, maybe more as some are there anonymously, I've heard. If you have a stud pitcher throwing 90+ on your team, or opposing you, then there will be lots of eyes on your game. But the best bet is to have made contact with coaches before you get there so they know that your son will be there.
Hustle, stay positive, bring a big hat and those cooling towels for your son's neck. Of course, you're from Texas so the Phoenix heat probably won't mean much to you!
