Too bad you don't know how to read the large sign above the whiteboard. It lists EVERY CMP match date for the year. It is ALWAYS the 3rd Saturday and starts at 9AM . . . 9-10AM is their instructional part of CMP for shooters who are new to the CMP match. That is likely why they refused to let you shoot the match when you showed up at 9:30AM.
I will readily admit that the calendar is severely lacking in listing all the regular events (CMP, pistol, rifle matches, etc.). That is a legitimate gripe and one that the webmaster should address.
As for range officers, we are all volunteers and get paid $0.00/year for our efforts. Sometimes life gets in the way . . . illness, deaths, family events, vacations, work, etc. So yes there may be a few occasions when a RO can't make it and sometimes it comes at the last minute and a substitute can't be found, that's life. You obviously like to bitch about it . . . when the RO mandate (actually generated by NRA's range experts evaluating our safety after shots hit Carradonna's warehouse downrange from the pistol range) occurred myself and others ponied up and volunteered. Also apparently you don't pay any attention to the club's range rules either since they clearly state that there is NO SHOOTING before 10AM on the outdoor ranges on Saturdays! Only the CMP shooters were supposed to be on any outdoor ranges and as I stated above, they were undergoing instruction about the match.
As for the handwritten sign about the ranges being closed, the folks that manage the CMP match wrote that sign on that paper and chose their words poorly. That is a legitimate gripe and perhaps was the reason that we only had ~8 people show up to shoot on the pistol ranges during the 2-1/2 hours I was there today.
I was the range officer on duty today from 10AM to 12:30PM when I was relieved by another RO. I turned the steel sign around at exactly 10AM. Had I found you up there shooting in violation of the range rules, you would have been facing the BOD for possible expulsion from the club. Again you apparently don't know how to read signs and therefore would be much better off elsewhere where you can join someplace that has no rules for you to violate.
