Libraries often sell books for cheap. I've purchased paperbacks as low as a quarter and hardcovers for a dollar.

Worked quite a few summers in the soda/hotdog satellite snack bars as well as the main area in the sausage sandwich/lemonade stands. Can't remember the name of the dude that was the main child worker wrangler. But he was always riding around on a 4 wheeler ordering us all around. Joe maybe? Been a looong time.
