Yes. There's not a real good reason as to why there isn't one. I can say that I cut a lot of brush, but at the end of the day, I was not willing to be the only guy doing stuff. Scout had taken up the challace a couple of years ago. Can and should GAF field an NCOWS posse, absolutely. I may be persuaded to pick up the challace again, if I had 2 dedicated individuals.
It's easy enough to form an NCOWS posse. I know local shooters here would join in, but joining in to shoot, is different then helping build something.
