In Essex, there's Burnt Dick Hill, which is in Constable Country, and Fingringhoe, jst south of Colchester (I'm going there tomorrow). We've discussed the Scunthorpe-Penistone-Clitheroe route before, but no-one has yet done it so far as I know. I think perhaps I might try to do it next year, if I have a few days to spare. A pal lives in Brigg, and Mrs. Wow's sister lives not a million miles from Pendle Hill, so I've got accommodation guaranteed.
