I might be showing my age, but we used to take guns to school all the time. When dove season started, I used to take my shotgun to school on the school bus and keep it in my locker so I could go hunting after school. When I became old enough to drive to school and owned a truck, I used to keep guns in the truck in the school parking lot.
I don’t guess how old you are.
I used to carry guns to school and around the neighborhood in the 80’s.
