My son played for the Griffons last summer. It really prepares them for minor league ball with the heat, the long bus trips, living with a host family, playing baseball 6 nights a week, often double headers, and learing to manage their time/diet/workouts/etc. Its very different than living in a college environment.
He will have a great summer and meet some wonderful people. You can listen to most of the games over the internet!
Good luck to him!
