Shooter drills. Makes the duck n cover drills look rather stupid in retrospect! "When you see the glow, duck below." This was also the time when kids drove to high school with a rifle or two on the gun rack in the back window of the pickup, and a pistol under the front seat. Nobody was without a pocket knife. None of this terror happened then. Old folks used to say, quite a few years ago, "People have changed. People are different." Something has sickened us. Kids are precious, they're fascinating, they see things we adults can't, and they grow up too quickly. Fear stays with you for life, and beyond. There really is such a thing as generational PTSD.
