Did you have a shooting RANGE in your high school? We did.
As a kid riding the bus, me and my older brother brought his .22lr Remington Rifle for Rifle Club and I got to carry the box of bullets ... I was in fifth grade and he was in seventh. Bus driver never even blinked when we boarded the School Bus ... in 1950. A SWAT team would probably gun us down now adays.
Yes. In the basement of the school. And 50% of the guys INCLUDING TEACHERS TOOK off on opening day of deer season.
