Actually, I know where there are TWO of those within driving distance. Those are the parks we go to.
I haven’t seen one in California since the last one I fell off of- about 1965.
The playgrounds now all have padding underneath for soft landings - not the sand or dirt we fell into. The elementary school near my home is ripping up the padding under their play equipment to put in even MORE padding.
Those kids won’t have scars like we did, which I proudly wear to this day.
