In 1974 my 9th grade chemistry teacher got invited pheasant hunting. He asked us boys if he could borrow a shotgun. Next day about 12 showed up in the classroom and he tried them all for fit and function before selecting one.
If we were going hunting after school, we left the gun in our locker. Rode the school bus with them, too.
Hell I forgot a shotgun in my car once and took it to school. Principle called me in and just told me not to forget again. This was in 2001 in south Louisiana.
