I do love watching a winter sunrise from a train or bus, but I still feel that 5.30 is a bit too early a start for the privilege! But it was a glorious day for walking, cold but sunny, and in a way going and walking 18 miles is the right thing to do just after Christmas, because the problem with Christmas is that you never leave the house*. But I'm sleepy now!
*Actually I got cabin fever on Christmas Day and went a walk as far as the Parrots Parish Church, a mile away. But I didn't go out on Boxing Day.
