I am not certain where I took this photograph. It is somewhere in West Yorkshire, that's for sure, and I must have taken it about 30 or 40 years ago. As so often in this part of the world it is the roof line that is the centre of attention. Shapes fight shapes, orientations have a pleasing diversity, and ostentation is a stranger to these lands and these times. With its grey skies and black earth, all the attention is concentrated on a strip of activity - like the legs of an Irish dancer.
