I lived in a place where the nearby park swings were made of iron rebar. As a 5 year old, I remember pushing my sister's swing a bit so she could pick up some height. Only to have the swing come right back and smack me on the face. It threw me and I ended up with a bloody lip. I'm lucky it didn't hit me so hard that I ended up dead. I wonder how many kids ended up hurt before they decided to change it. This was around 1972. "The good all days", huh.
