Rochdale has so many of the makings of a lovely town. It has a town hall that many a substantial city would curl up and die for, it has a rich social history (it is the birthplace of the co-operative movement), and it has a sprinkling of fine old buildings. But it also has dual carriageways that carve their way through the town, and car parks that seem to spread for miles. That is the town hall in the background. That is the car park in the foreground.
