You can get on a PG team by calling PG. They are really a second tier option IMHO. You are better off getting on a regular team going to Jupiter. The teams that PG puts together (other than the travel teams PG has, which my son played on, I am talking only about the teams they assemble specifically for Jupiter.) are not as heavily watched or scouted as the other teams. If you have schools that are already showing interest and want to see junior at Jupiter, PG is fine, then they can find you and see you. However, many times its the coaches you didn't count on seeing you that "find" junior. This was the case in my sons case. Juniors current coach just happened to see him, the rest is history.
Best of luck.
