Agree, the older groups are much rougher. In City Heights they stop at u15 because it gets to crazy.Mexican League (Santa Ana) has been great experience for my kid at younger ages. He played indoor and on Sundays, whenever it didn't interfere with his club training or games. Kids and parents were very kind and supportive. Some teams we played were great and some were awful, and so are the fields.
Very low coast to play. However, at U14 it became in issue with over competitive parents. Constant screaming at refs, players, few physical altercations between coaches/parents.
