We lived on Long Island, Elmont - Valley Stream when I was a kid in the late 50’s.
My older Brother took his Bolt Action .22 Rifle to School. He was in the Shooting Club. Nobody batted an eye.
I think my Parents bought the Rifle at Sears.
My son went to Chaminade. Graduated 2 years ago, and was on the riflery team. They are one of the very few that still have one.
In fact, the team sometimes competes remotely, with other schools from upstate. Each team shoots at their own school, and the judges record the official scores, with the teams never meeting in person. SAD.
