The canal was always there in my memory. Sometimes a lonely desolate place, sometimes the sunny light feeling of walking along by the water. You could walk for miles of changing landscape, along its edges and lost waterways, crossing countryside and the hidden parts of the town. From the windows of a train travelling across the valley to Manchester. From the window of my school bus, as it wound its way through the outskirts of the town. Where the chimneys remain, when the clouds hang across the Colne Valley, the canal looks back at me.

It is at this time of day that the city begins to reveal itself. When street lamps are lit, exposing walls and the narrow passageways between buildings. The lights illuminate brightly so that the wall seems cast in yellow stone, and the shadows of overlooked corners steal away to find new hiding places.

I am thinking of a photograph on a beach somewhere on that trip to Wales. Dark clouds and grey sea. There is synchronicity in the image; our faces are together, touching in the half light. When photographs were still like slips of chance on the paper. Thinking about being outside as night fell in the mountains, sharing a bottle of wine; jubilant in the almost total darkness, with no lights to guide us home.

Connected to our beginnings and ends, people wander through cemeteries to be close to those who are no longer here. Each city, each place, contains the imprints of all those who have walked its streets and all those yet to come, the ghosts of history who are with us even now. In some places we are more aware of them than others.
