I guess it depends on what you intend to see while in WNY. Letchworth is one of my favorite places to camp, but it's quite a distance from the Falls, if that's your intention -- there is quite a bit to see and do in that area, though.
I also enjoy Allegany State Park which is a little closer, but still over an hour away, and there is literally no cell coverage, nor TV coverage in the campgrounds. That is the reason that I go there, frankly, I'm totally unplugged which is very nice once in a while.
I never stayed at Four Mile Creek... maybe next year!
