We were driving along a coastal road in Cork, Ireland. Ahead was a warning sign of a deer, black on yellow; the road signs in Ireland are quite elegant and charming. The sign was on the side of the road, behind it was dense green foliage, including explosions of purple rhododendrons. There was something about the lighting, the colours, the bend in the road that would have made it a great photo. But there was no way of taking it, then it was gone.
