One evening I was up at Everett for an aviation opportunity and, things were not looking good because the shot I was after was looking like it was going to be thwarted by a late arrival and the setting of the sun.  As it turned out, that provided a far better shot than I expected.  The sunset illuminated the clouds, and they provided great light for the arriving aircraft.  While I was waiting, I did look behind me and saw that the sky was glowing beautifully.  There was no way I wasn’t going to get a shot of that.  Sunset shots are rather passé but why not?
