Spdrun: I don’t know if it’s around anymore or not, but the NRA ran a program when I was a kid, using WWII surplus M-1 Garands, teaching gun safety, gun use and how to become an accurate shot. It was taught (in our area) by some former soldiers and Marines, including a Gold Cup shooter. You could also purchase the rifles for like $100, which was stupid cheap, even back then.
I think it was called the Civilian Marksmanship program.
I’d be all for that How Shit Works class, too. Seeing the vacant stares you get from kids these days when you attempt to show them something mechanical is terrifying. If the power went out, half these little SOBs would starve cuz the electric can opener doesn’t work.
