So where are these guys? The split rail fence indicates a district with native woodlands, almost anywhere in the Eastern States up to the Plains. The evident success of the crew suggests to me high growth industrial towns nearby. So I'm guessing in a very wide corridor somewhere between Philadelphia and Chicago. Can anyone focus on the location?

They are setup for a wide variety of work ie timber frame, full frame and balloon frame to finish. Two miter boxes and full kit for all indicates high production.
