I wasn't going to post, but what the hell-
I've lived in a half dozen states, been to 3 times as many ranges and have never seen mandatory brass catchers. While we need to be courteous to others, be responsible stewards and foster new shooters into the sport, some of this stuff is just getting way too politically correct for me.
What are we going to complain about next, it's too hot, we need fans .....it's too far to walk out to the target, we need auto returns.......it's too bright, we need more shade.....it's too loud, well I would agree with needing a suppressor, but you get the point.
A lot of this stuff sounds like my 6 year old daughter, but even she is harder than that and knows to expect brass from a gun!
All the analogies already posted I agree with; if you don't like sand, don't go to the beach, if you don't like hay, get off the farmers daughter and if you don't like brass don't go to the range.
Bottom line- brass catchers are nice, but not needed. Be courteous to your fellow shooters and keep the mandatory items to true safety concerns.
