First week of my vacation, I went and watched my little cousin play in a middle school game. It was a one-ref game, with scorers and timers who were 12 at the oldest. Toward the end of the game, there were a few situations where a basket would be wiped off b/c of a travel, or a close one was really a two, and the scoreboard would show it wrong. My cousin's team won in the end, but I'm not sure how much they won by!
