This one from SmilerFTM. I realised after I'd posted it that the message I had replied to wasn't shown.
Just did this run today (twice) and had a great time. The run from Helmsley to Stokesley on the B1257 was particularly good fun while the back road from the A171 through Castleton and Hetton-Le-Hole was also bloody marvelous however care had to be taken on that particular road as I didn't want a sheep shaped indentation on the front of my 5 (plus it was a bit wet). I will be doing this run again in a couple of weeks or so, work is going to prevent an earlier return, and so will try and take pictures next time.
