Who remembers roller skating? And did you have the metal skates that screw-tightened onto your regular shoes?? With leather straps around your ankles? And the slide-to-size part got rusty??
And what happened when you lost that darn key?
Do kids roller skate around their neighborhoods anymore???
Yes, they are called skate boards. No key.
I made my skates into a skate board back in the 50s
