Great NY cab driver story. I had just moved back from Chicago and of course left my purse with a few hundred in cash, wallet, credit cards, etc. in a yellow cab. I cancelled all the cards, got a new driver's license, and went through the trauma of hoping no one used my keys to break into my car or home. A few weeks later I got a call from a very irate woman. Her son was the cab driver and he had traced me through my library card to a Chicago address which led him to my previous company which led him to... until they found me. I picked up the bag with EVERYTHING in tact. She gave me a long lecture on how her son was the exception to the rule and how hard he had worked to find me. I gave him the cash. He gave me a warm and fuzzy - people are good.

Another true NY story:
A few years ago, a LI family went on a picnic with a carful of aunts, uncles, kids, picnic baskets, etc. Along the way they had a flat. Everyone got out of car on the LIE and the tire was changed.
When they arrived at the park, they suddenly realized that their baby and infant seat were gone. While rearranging everyone for changing the tire, the baby in the seat was placed on the roof of the car and forgotten. Instant panic!
Meantime, a man driving along the LIE saw a perfectly good infant's seat lying on the side of the road in the grass. He pulled over and found baby and seat. The baby was unharmed - nothing good sits for long on the LIE including broken down cars. All were happily reunited. Makes leaving a fiddle behind look almost normal, doesn't it?
