That’s an automatic suspension and trip to jail now. We kept rifles and shotguns in our lockers.
I don’t remember anyone having a rifle or shotgun in their locker (we had those stacked lockers that wouldn’t hold a typical longarm anyway), but the parking lot was littered with gun racks holding a variety of weapons. No one thought a thing about it. That was the norm. It was common to hunt right before or after school. Every high school student took a semester of hunter safety, too.
