I don't know, kids these days. You should have seen what we had to contend with in the 60s - huge lumps of flesh mangling metal, swinging at terrifying angles, throwing small children off in all directions. And no wimpy rubber mats to catch them. Sometimes, I wonder that I survived.
reminds me of when I was a kid in the UK, there was these places that was called 'funhouses' where kids was supposed to play, I was seriously terrified of dying. I'm unsure if it's my memory and/or if I was just too young
the other scary thing you could do with it was to grab hold of the plank on the up-swing, which would boost you high in the air. you had to have a nice touch of judgement on where you let go, if you didn't want multiple broken bones.
