For me the colors are reversed. Bowling is fun but I can't imagine doing it as a sport. (Nothing against bowlers; I just feel like it's so repetitive. In other sports the scenario is different every time but it's always the same in bowling.)
4 and 8 are always the pins that don't get knocked. I'm a terrible player.
if you follow this diagram and just leave the 7 pin standing, then you should pull out your HK USP .45 tactical and take out that pin with hollow point rounds. problem bowling?
