"Back in the day" (1970's as well)...
I used to ride my bike to school. Without a helmet. And never once locked my bike to the rack. Elementary and junior high (middle school).
Here's the one that'll get ya...
I used to carry my .22 rifle to school. Many of us did. we would shoot bottles and cans at the vacant property and ball fields. Even had teachers who would participate.
We kept our rifles in our locker. And I remember kerping a box of shells in my locker.
Even had one teacher bring his muzzle loader in and allowed some of us to shoot the little cannon.
My God we've become a country of such political correct wuzzies.
