Seoul,
It sounds like your summer stay is mainly on the west coast? When does your son turn 14 yrs. old? If he turns 14 before Aug. 1 of 04, he would then play on a U14 team. If he turns 14 after, then he is a U13.
I coach a U13 team, called the Tidewater Drillers. We have players from Va. Beach, VA to Richmond, VA. If not U13, I have plenty of contacts for U14 teams. Send me a PT (private topic).
Here is our web site on Eteamz.
