Well that’s it, summer is finally over. There is still plenty of green in the leaves, but you know it’s a perennial losing battle. Once again, as I find myself looking out of the window on the trains to and from London and Brighton, which has some of the most beautiful countryside in the country (the view from the Ouse Valley Viaduct breaks my heart, in a good way, every time I see it), I reproach myself for not having walked in them, up hill and down dale.
