We lose our rights because of a few idiots. Another place I shoot, the EPA is looking to shut it down, because of the shooters who bring junk up there, like old TV sets and washing machines, etc, to blast. Fine and dandy, but bring a garbage bag, and take your crap home with you. But they don't. The place looks like a garbage dump sometimes, and the forest rangers are stuck cleaning it up. The few slobs give the gubmint excuses to take our rights away.
More interesting than the golf course is the nearby airfield. Probably uses VFR rules. Circling patterns would very likely overlay the range safety fans for even weapons with a lesser range.
It might well have been shut down for political correctness or noise complaints.
