You left out a key piece of information...we didn't wear helmets, either.
Mid 70's for me, we also built ramps to jump off out of old pieces of plywood and rocks or random pieces of brick. We also had BB gun fights and orchard wars. Getting hit by an unripe avocado hurt like hell. Ice plant sledding was another fun one.
The funny part is our parents didn't really tell us not to do those things, but had no sympathy for us when we got hurt. Basically, they would just say "Well what the hell did you think was going to happen?"
Were fortunate that we live in an old school neighborhood and the pack of kids just roam around and usually make it home before dark. The main difference between old school then and now is that I can track my kids on Life360.
