That's a really nice range! I can see why the demand to get it would cause a 2 year wait, looks very nice.
It's a shame to hear about the public lands there. We have two somewhat nearby me here in MD but I haven't been to see them yet, so we'll see if they fare any better. I will say the Park Service ranges near my old hometown had a bad run there for a while with people shooting at garbage/old appliances/etc until the Service basically said they couldn't afford to clean it and they'd shut it down if got that bad again. Now there's a volunteer group that keeps it nice and helps to keep out the riff raff, it's been nice the last few times I've visited.
From reading about the wait times, and knowing the private ranges here have about the same, I'll assume its about the standard probably nationwide. Long lists and high fees probably help keep the membership friendly/keep out ne'er-do-wells, although it does make it a pain when you don't plan on living in the same area for more than a few years.
