After class, several friends and I would go to the trunks of our cars and put on hunting over-clothes. We would then take our shotguns and go to the gym, where the gym teach would take his shotgun out of his locker.
The whole crew of us would walk through the school, out the front door to a big field across the street. Lots of pheasants in those days. We all would do pretty good most of the time.
Only thing ever said by the principle was “boys, be sure those weapons are broke open.”
It wasn’t out of the ordinary.
The principal knew guns were not a problem.
