It was an unbelievably mild and dry mid-November evening when we left Plasterdown, the moon coyly hinting at its presence from behind the clouds rather than deigning to make a full appearance. Up Pew Tor we went, the three of us, failing yet again to find goldfish in the quarry - they must be long gone. A real surprise was what appeared to be a levelling point set into a boulder on the tor: a surprise because it bears the stamp of the Hydrographic Branch of the Royal Navy. There is more to determining mean sea level than one imagines! Out, then, towards Merrivale until we met the Grimstone and Sortridge leat, where we sat for a cuppa, admired the night sky and fulminated about Brexit. Onward we went along the leat to inspect the aqueduct dedicated to one John Wills (1958 - 1987), though the grass is now encroaching on his name. A final pause at the cross for a photo opportunity before heading back down to Plasterdown and thence to a quiet Whitty.
