Not quite in the league of Herbie quizzes, but whilst waiting for a very slow volunteer to ring up my purchases in Oxfam, I idly glanced around and alighted on this. Unfortunately it was behind a pile of sofas so the angle from which I could photograph it was rather constrained, hence the reflections.
I am terrible at identifying locations, but it looks vaguely familiar even to me. I'm not saying where I think it is though as I may be wildly and embarassingly wrong. I will write it on a slip of paper and put it in a sealed envelope, and reveal my guess only if the Herbies (for it is bound to be they) confirm it. Please feel free to tell me though if you get in before Kath and Neil.
Only four days in and a waterways-related post. I'm as surprised as you are.
