Better leave it alone. Sometimes it makes individuals with a little more income very happy to do something very special for another person anonymously and wanting nothing in return (Ken included). One thing I/we have practiced over the years is Random Acts of Kindness. Just watching the look on someones face when they receive something nice beit a tank of gas or a paid for dinner without ever knowing who it came from makes it all worth it and that pales in comparison to what we are talking about here. I would be willing to bet what Charley did made him happier than many of the car purchases he has made. Certainly the Isetta.
