This is an offset multi-cache in Attleboro. The posted coordinates are virtual and bring you to a historical sign located outside of the Attleboro Industrial Museum. You do not need the enter the museum to get the information from the sign and can view it from the sidewalk. The sign talks about some history of the area and how this museum came to be.
To obtain the cache coordinates, input the four years found on the sign in order from earliest to most recent into Certitude. The first three years can be found in the main description of the history of the area, and the fourth can be found on the bottom right of the sign. A hide hint will be provided in Certitude once the answer has been input. Hope you enjoy.
Note: there is a date located in the town logo on the top of the sign - that is NOT one of the years you need, so please disregard it!
