There was a survey crew doing the shopping center where we park. I got pix of the pins. Here is the entrance to the roadway.
The two pins are on either side of the 20' roadway out into the swamp. On the right, it is the white paint area a foot
or so to the right of the big obvious pipe (that I'd thought was the pin). On the left, it is below the white flagging by
the utility pole.
