Wooden playgrounds? Listen here, kiddo. In my ancient youth playgrounds were made out of metal. Anchored to concrete!
You haven't lived until your butt rode down a metal slide on a hot sunny day. Or climbing on a metal jungle gym. Or riding a metal seesaw. Yet somehow, Generation X survived. Maybe that toughened us up.
The coolest thing, our school where I went until second grade, on the playground was a slide that was a good 15 feet high. Metal, of course. But they put a layer of Teflon on it so you really got some speed. At the bottom, the edge was turned up so you went flying off the slide and caught some serious air time. And you broke your fall landing in a big mound of dust. Guaranteed to dirty your pants.
Even better, after it rained it turned to mud!!!
Down the slide, wheeeeeeeeeee!!!!!!! Three seconds in the air, defying gravity, then your butt lands in the mud.
After recess, teachers hated the mess it made, but you couldn't wipe the grins off our faces.
See, Skippy? We knew how to have fun! Now pick up your phone and get off my lawn! 8)
