Working from home, as I have for the past 20 years, you have to keep yourself moving. Most days I try to walk at least a brisk couple of miles, going straight out of the front door, but sometimes, if I have to take the car on some errand or other, I park up and walk from there. Back in October, I found myself near the Leeds and Liverpool Canal, on the Rufford Branch, which heads off north towards the River Douglas and the Ribble estuary, leaving the main canal to wend its way through Lancashire and Yorkshire to Leeds, 100 or so miles away. The combination of industrial architecture, and nature makes canals special. Out here in rural Lancashire, the waterway is a corridor of loose vegetation, a place for birds, and animals, cut through largely flat, intensive farmland. Here the bridges and lock gates seem like interlopers on a natural landscape, but of course the canal itself is a built environment, a remnant of the Industrial Revolution. This section was built in 1781. The Rufford Branch is still navigable, but on this bright morning I saw no boats, only the winter's first geese, and an occasional flash of fish. I used two different Kodak films, TMax 400, and Portra 400, and my favourite camera, the YashicaMat 124G, which takes square images.
