Street and pond hockey.
When my friends and I were in 5th grade, we beat some 7th/8th graders. They couldn't believe that they lost. We beat them worse the second time. That was it in my school, nobody would play us after that.
A few years later, we played a few college club players in a pick up pond hockey game. We beat them because I recognized a local college goalie that I had seen in action and he played on our team, but it was close game.
I stopped playing at 13. My high school didn't have a team. I retired with all of my teeth.
Everybody but Alko beats me. Congrats to you all!
