So confident am I of the location above, I'm going to post the next picture without Skippy's acknowledgement.
(Bet Langcliffe would have identified the above photo if he'd seen it before me.)
This morning's run took me past the well known view point in the picture below. It was a beautiful morning and quiet up there as I arrived. I noticed someone had attached a poppy to the trig point. It reminded me on this important day that, despite those seeking to disturb proceedings in London, there really is a majority of decent, respectful people in the United Kingdom.
Anyway, the location is pretty easy really. (There is actually a caving connection, although admittedly a bit tenuous.) Go on, someone please post where it is.
