I live in Maryland. Mason & Dixon were hired by the Penn and Calvert families to survey and mark the lines between their land-grants. (now the border between MD & PA and between MD & DE) You can see one of their markers between MD eastern shore and southern DE.
Also see my tag-line... which is a quote from my father.
Neat story. Thanks!

I too live in Maryland, where I occasionally see bumper stickers which cry out, “It takes guts to be a Democrat in Garrett County.” Out this way you can see the terminal M-D marker at the boundary point of PA, MD, and WV. I assume there’s also one at the boundary point of PA, MD, and DE but I’ve not seen it.
