Ditto on what Herodotus said.
The public ranges owned & operated by the Missouri Conservation Dept. are top notch & first class establishments. The range officers are not only VERY safety conscious and not at all bashful about taking appropriate action, they are generally all enthusiastic hunters and-or shooters themselves. VERY good people to talk to and associate with. All government employees should be so competent.
Safety at "open ranges" is a ticklish thing, especially when you are around people you don't know. When I'm in a place like that, I constantly watch those around me for unsafe practices. In the event that I see something pretty flagrant, I usually just pack up & leave.
Safety wiht firearms must be learned. How we go about educating our armed brothers & sisters to safe & courteous handling of weapons without offending them and possibly initiating an "incident" eludes me. I just have to conclude that SOME of the ones I've seen either may already have been or someday will be a feature story on the local "10 O'clock News". I just know that I don't want to be around (either being interviewed, or being loaded into the ambulance) when the cameras start rolling.
