Im quite happy to let younger folks come out and enjoy our sport. There are plenty of places that accept them with wavers etc....let em. I will align myself with groups that play more in line with what i enjoy. The mature crowd is just by far a better environment for me. Shooting hapless high school kids just isn't fun.
I totally understand the delicate balance our equipment sits on. I would hate to see some place that takes kids have it get out of hand, for the sake of the injured but more for the sake of the sport and the legal access to our equipment. So i find it exceptionally hard to spend my dollars at those places. That is the only real vote i have.
We all need to be responsible, and with that we can all enjoy our sport for the years to come
