Bridge over troubled waters

I seem to be on a Canal Rocks theme at the moment. It is the closest part of the coast to where I live and I can duck down there in a few minutes, so it becomes the choice when I make a last minute decision to go out. This was taken Friday evening, just after the sun had set. About 5 minutes after the sun sank behind the rocks the sky came alive. This lasted for about 3 minutes.  Ideally I would like to have been a couple of metres to the right, but I would get very wet if I tried!

The title of the post relates to the fact that the water under the bridge is always moving, even on the calmest of days.
