Nah there's still plenty of "An area that's mostly nature and you can just walk through and enjoy it" but the vast majority of them were set up a hundred years ago so the reality is that most of them aren't even remotely close to population centers anymore. This means if you want to walk in a park, first you must drive there. Also in many places, staying past sundown is not allowed, as in the cops drive in (like they will actually drive around on the grass if they physically can!!) and sass you.
