|Mile Marker, 1768, photo by Midge Frazel, 26 Oct 2014|
Found outside the Wayland Historical Society in Wayland, MA an intact "mile marker" indicating that from that location to Boston is 19 miles (by horseback). This is the GPS of its day!
The back of this marker is rough and it looks a LOT like a gravestone that was never used. I think the letters have paint on them. The person walking ahead of me laid their umbrella on it while they opened it up. I almost screamed.
