Some accounts say that Franklin drove along the route with his version of the odometer attached to a wheel of his wagon, and that he placed a wooden marker every mile. Other wagons were said to follow shortly behind him, replacing his markers with carved stone ones, some of which survive today.
The known locations of six markers in Maine:
- WP6 - Scarborough (see attached photo)
- WP7 - Westbrook Street, South Portland
