Probably places like Missouri and Arkansas in our neck of the woods could do a pretty good job of it but Oklahoma can’t even keep roadside parks and itty bitty historical monuments open. They can’t even keep the roadside historical markers maintained. This state is too poor to pay attention or too wasteful.
I see your point. In our travels we have run across some pretty crappy state parks, Ohio is one example. But in our neck of the woods, ND, SD, WY, MD & MN they are quite good. In ND I’ve found county park infrastructure (rest facilities, camp grounds, etc) far superior to the Roosevelt Park in ND.
Also the staffing is people friendly in state facilities, where national parks they tend to be animal friendly, and some of the staff will not hesitate to tell people that animals were there first and the place belongs to them.
National Parks have completely reversed what T Roosevelt imagined. He wanted to preserve a bit of nature for people. The lefties changed that to preserving nature for animals, to hell with people.
