I remember when .22 LR was less than fifty cents a box and even though I was only 12 years old I could buy 'em myself at the hardware store.
Along the same lines: We used to have Christmas programs in grade school and were allowed (expected!) to sing religious Christmas songs. After the program we exchanged gifts with our classmates. I once got two whole boxes of .22 ammo.
Imagine either one of those things happening in a school now.
