Where I live our town rec leagues go into the late teens, and we also have town travel soccer until players graduate high school. My older son became a serious tennis player, but continued to play town travel soccer with his buddies until college.
My youngest is a totally different story. By high school he had specialized completely and only played for his club soccer team. He never played a minute for his high school team because his club/league forbids it. He trains 5 nights a week and plays matches on the weekends. The travel is extensive and expensive. The club basically owns him for 10+ months per year. I’m ready to hop off the merry-go-round, but he wouldn’t have it any other way.
