My grandfather used to (or so we were told) bury money in jars in his backyard. He had a map for where they were, and every now and then, he'd dig them up and move them (redrawing the map). I don't know if this is a true story or not. He had a lot of gold coins, and that may be what he buried. He also had money in several different banks partly because he didn't want to put too much in one bank and lose it and partly because if the bank was giving away something to people who opened accounts, he'd open an account. By the time I remember, he worked in a hardware store and my grandmother did alterations at a laundry and cleaners business. He'd done a lot of different kinds of work in his lifetime, though, and never got over the depression, I think. They lived in a small three-bedroom, one-bath house in a not very good part of the city.
We used to get phone calls from some guy looking for his mother. I finally figured out she had the same number as us, but in a different area code. She lived in a town about 20 minutes away, but somewhere between here and there, the area code changed. I never could figure out why he didn't know his mother's area code and that he needed to dial it.
