I was out 'happy-snapping' yesterday when I encountered the lock-keeper at Picketts Lock 'having a good sweep-up for Christmas' as he put it. He and his dog posed and I posted the picture and wrote the caption to that effect. Only later did I discover that an earlier entry showed the self same man and dog with the comment 'the old man who lives in the cottage seems impervious to the litter'. Well, evidently, such is the power of Geograph that Alf has seen the error of his ways. Who shall we tackle next ?
