I happened to glimpse this roadside scene as I was traveling by car to another location. It was one of those occasions where you are in two minds whether to stop and investigate or not. After parking and walking back to this spot, I was immediately struck by not just the similar tones, but also the matching lichen growths on the wall and tree. As they were in shade, under a clear sky, they both radiated a lovely blue grey colour. The comparison between the hard, ordered, structure of the wall against the chaotic patterns of the branches was intriguing. In short, I'm glad I stopped. Photo © copyright by Graham Chalmers.
