This reminds me of somethig that happened to me......

1 block from my house I found lying in the street a driver's license and a credit card....same name. I used the address on the driver's license to mail them annonymously back home. I was actually AFRAID to identify myself as the finder fearing that if harm had come to this man (resulting in his cards being on the ground) that I would have been the PRIME SUSPECT!!

I would have turned the card in, but I might have kept the $20 in the dispensor .
