2021 carries on where 2020 leaves off. There are changes and closures, and I am trying to reflect these (where I know of them) in the walk narratives. I am tweaking typography as well as topography (well, topographic description) to make both editing and reading a bit easier. First up, the London Summits Walk has been given its spring-clean: demolished sighting-points and closed refreshment-points are removed, and typos and similar infelicities, where spotted, have been edited. The Coal Tax Circuit has been given a similar spruce-up, bringing internal consistency to the pages.
