Here is one of the harder to find Yorkshires. I only know of two to exist. I turned both of them up about 12 years ago. I bought them from a lady who had found them in the mud, in a flooded basement of a house on the west side of Cincinnati, (Price Hill). She wouldn't give me the address, to this day I still wonder if there are any more there. I cant remember exactly who I traded the second chip to.
