Passing the time

Well, what else is one supposed to do on a journey round the M25 which is supposed to take 2.5 hours but actually takes 4.5 (as ours did last Sunday)?

. . . so here are some pics taken at the Dartford Crossing over the Thames, from the Queen Elizabeth II Bridge as the traffic edged along painfully slowly. The long views look west towards London, where various towers, including Canary Wharf, were brightly illuminated by the low sunlight - but needless to say are not clearly visible on these fuzzy pics taken through filthy windows!
