Thank you, Thierry, Paulo and Eric.
Thierry - I hear you. In this instance, nature served up this scene.
Eric - Yes, I was suitably accoutred. More important, my friend Börkur knew where to stop/park, and how to orient the car (into the wind and away from incoming) so that I could mostly shoot out of the window. Just before these images, we almost had a head-on collision with a car driving bang in the middle of the road in zero-visibility conditions (nationality of said tourist left as an exercise to the reader :-).
