Setting off to see one some of the most spectacular stone rows on Dartmoor in heavy mist is not very clever. But we did it anyway, amid dreary dampness; perhaps the name should have given us a clue. Well it certainly drizzled, but in fact when we finally found the stones they looked rather haunting, shrouded in the mist which lifted and sank again, bringing them in and out of view. We then headed down to the Plym for a swim in what I call "Warhorse Pool" - because it's just below the old farmhouse at Ditsworthy Warren, which played the part of the family farm in the Steven Spielberg film. The river was running high, the colour of cola, and as we swam upstream we could see the large terminal stones of the row standing like eerie figures in the distance.
