The posted coordinates will take you to a sidewalk along Minnesota Highway 71, aka Mill Street. At this point look across the street to the West and you will see some old brick buildings, three of which have a date of construction near their peak. (The building to the right is much shorter and newer.)

F= # of letters above the date on the center building.
