Had a friend of mine break down while out hunting and a man and his son stopped to help, ended up towing them out of the woods many miles back into civilization. Wouldn't accept any money for helping but just said that if you come across someone in the same predicament just return the favor. To make a long story short, almost 20 years later in the same general spot where he had broken down, he came upon a disabled rig. Remembering what had happened to him he stopped to see what he could do. It turned out to be the original helpers son, who finally recognized my friend. A great example of what goes 'round comes 'round!!!
