I work about 3 blocks from a railroad ( Frisco ) and on the other side of the tracks ( about 4 blocks )was the Gasconade Hotel built in 1889 ( burned 10 years later ). So I thought that there should have been some kind of movement around there. The house's in that block by work were built around the 1930-40 and as far as I know they have never been detected before so I'm working on permission for the whole block. Had my first "NO " yesterday at the end of the block. This coin was pulled out of the back yard .
