Finding change as a sport: http://www.cnn.com/2009/US/02/06/found.money.family/index.html

OK, for a while, I wondered if my picking up change was a sign of insanity - and my partner would sometimes insinuate that it was. That is, until we emptied out our change jar and had $250 in it for our vacation. He's now converted to this simple bit of thriftiness, and I'm realizing that my habit of scanning the floor for change paid off when I found $50 in the Port Authority one night.
