Been a few years ago, but SIRA, Southern Indiana Racing Association, go-karts, a street racing based organization, institued this proceedure, and as tensions were getting heated anyway, because they drew Karts from all over, I mean ALL OVER, it really put the "homie" feel back into racing, no more pulling 200+ miles, and having a chain break, or an engine sieze, or a hay bale jump off the curb at you, and you were screwed, you put it in your trash bag, and recovered, and business did pick up, maybe not always the same guys, but everyone "ran" the same number of races, or "counted" if you prefer, and it soon became the norm, and people became friends again, for me, my closest race was at least a hundred miles away, and we were running almost every,weekend, so a real job, almost was a thing to do, between races. Anyway, it was a hard sell at first, but soon became the "way" to do things. Bob
