On way back we saw a young badger running up a ditch to their sett. It then thought we could not see it and kept still but in our excitement we frightened s/he and it disappeared down the sett.
I have been walking in the countryside for decades and have never seen a live badger. It was really exciting and of course, I didn't have time to get a decent photo.
As usual the stunning countryside just outside London is empty. We saw probably 10 other walkers during the entire walk.
