For some weeks now a gleeful MrP has been reminding me of a trifling navigational error I committed en-route from the Corbett, Monamenach, to the Graham, Meall na Letter, just to the east of Glenshee.  At the start of March, having persuaded me to break my exacting training regime to do some gentle walking, Mr.P then proceeded to drag me up hills covered in manky cloud – a pointless exercise if ever there was one.  In the interests of getting a bit of peace and quiet I have decided to “come clean” over this minor mistake and relate the sorry “tail” exactly as it happened…(ahem).
