537 or so shooters , you are gonna have a few issues. Best match of this size I ever attended. Rockcastle is an awesome place to shoot and should be commended for keeping the chaos of such a large match to a minimum. ROs should be thanked for working in the heat and dealing with a huge variety of personalities , what a thankless job. They got a free match and a room? No way would I do it for that , NO WAY!
