Around here, there are a bunch of private parks in that you pay a fee to enter the park or you can purchase a membership. The fee is minimal and mostly just serves to maintain the park. These are privately held parks, too, not owned by local or state government.
As far as I am aware, they are able to survive on their membership or visitor fees. But major improvements do take larger donation.
Private park, where you can’t even walk without paying an upright fee? Sounds like dystopian late stage capitalism. If it’s a well maintained garden I understand, but a sqare lawn should be free put your foot on.
I think we're defining park differently. Yes, I mean a large maintained garden with maintained trails. Not just a blank piece of grass, which I wouldn't honestly call a park.
