During the evenings at Cannon Beach, we could see lots of lights out on the water.  Fishing boats were out at work and their lights were very bright.  I am not sure whether they only fish at night or not.  During the day, it would be hard to spot them without the lights giving you a clue since they were generally quite far out.  However, one boat was closer in than the others.  It was right behind on of the sea stacks near Haystack Rock.  With a lot of mist in the air, the light from the boat was diffused and provided a backlight to the rock.  It wasn’t lone before the boat came out from behind the rock and the effect was lost.
