For reasons best known to Blogger and which I don't understand, these photos are in reverse chronological order. So they begin close to the end of October and head backwards towards the beginning (and yes, it is very annoying). Also they begin at the end of each walk and end at the beginning.
At this point in my perambulations I crossed the county line into Hertfordshire to go up on to Therfield Heath. Things that appear high up therefore are and are in Hertfordshire. The mounds are the tumuli on the heath and the views are looking across into Cambridgeshire.
