+1 Hats of to all those who helped clean up. It's just inevitable that Memaloose may be closed and I wouldn't be surprised if Brown;s rock pit never re-opens.
I try to bring heavy duty poly garbage bags with me every time I shoot. What i do when I see any other party shooting around the same spot, I give them one of the bags as a gift, I think the "common sense" environmentalist shooters like us can encourage others by just handing them trash bags, it sends a silent message. We don't want our spots to get shut down!
