It's fair to call Barbara and Scott Humpherys penny-pinchers, and they are making sure their daughters end up the same way. The family scours parking lots, sidewalks and every other place you can imagine for for other people's lost money. "It's not so much that we need the money," Barbara said, "it's to show an example to our children. The more change you see, that penny becomes 99 more, and it becomes a dollar." "With the economy the way it is right now, it's important that they realize Dad is not this endless tap of cash," added Scott, a U.S. Army career counselor. I think this is a great thing to do with your family. It teaches resourcefulness, financial responsibility and that child hands are the perfect size for slipping between sewer grates.
