I come back inside, look at the map on the table and use my finger to trace the path of my sailing plan for this fall from Elizabeth City to Cape Lookout and back. Outside on the upper deck I still see the green marker. Then I see the red lights of towers to the north. A dark shape on the horizon, darker than the rest of the night sky, is Bluff Point, which I have sailed by a few times. Swan Quarter glows in the distance.
