Yeah, definitely some confusion! I was talking about the image IMG_0199.JPG, which is the first attachment (the one on the left) in post #82. The coordinates displayed in that image are 41.71200, -75.05658

I would agree that looks more like it. I wonder why the fourth photo has different cords?
In any event, if I run from Marker 10 in the Warren grove area to that rock the line misses some point by 600 feet. So that tells us his line was not straight after leaving south jersey.
