The first and very helpful clue was in the selected farm photo itself. The bridge to South Park appears in the gap between the farm house, on the right, and the barn, far left. This we noted. Although a small part of the farm portrait, the bridge was in good focus and so we could “read” how its piers were sitting. The red arrow leading to the bridge in the farm photo approximates the line of the red arrow drawn onto the satellite aerial above it grabbed from Good Earth.
