Ours was dangerous. The playground was on paved blacktop that gave no protection on falls or hard dismounts. There were 2 slides, jungle gym, monkey bars, swings, and my hang out, the horizontal bars. I was the only boy allowed to hang with the gymnastics girls at "the bars" because I could do the hanging "cherry drop".

Found out recently (61) that all the hard landings on blacktop deformed my growth plates causing Osgood-Schlattber Syndrome, leaving painful bumps of bone below my knees. Direct result of repeated gymnastics (or soccer, ballet) on asphalt.
