Posting a pic from one of my last digs in the Spring.
Dug a railroad plate from the Port Hudson & Clinton RR, etablished 1833.
Of source at about a foot I was already counting on a shell!
A few minutes later I got the breast plate.
Since I like to keep a theme when I dig, the next hunt I found about a 5" section of rail to go with the railroad
plate. Glad it wasnt an 8' section!
