Fitz,
It's always a bit of a challenge that Harknott Pass, especially from the Eskdale end. It's the steepest road in Britain, with a 1-in-3 on the hairpins neart the top. It's a case of keeping the revs up. I always manage it in my Fiat Puno 1242cc, although in your vehicle it's a bit more of a sh1t.
Burnmoor is superb, as you found out. Lonely, open, desolate, yet with inspiring views.
I'm glad the impatient tw@t who tried to overtake you came to grief, and hope his axle and sump is bvggered.
Keep up the Eskdale/Burnmoor enthusiasm - spread the word.
Cheers,
TE.
