Nice pic Dave, I did the same run on my candy red roadster only a month ago. A Norton Owners Club run by the Shropshire branch, and I was the only one on a Norton! Also the only one to get a clear run up the pass by going to the front of a traffic queue at some traffic lights at the bottom, heh heh. The run was to a classic bike meet at the Old Stores cafe near Mold, 15 ish miles further North, and a better class of biker cafe than the Ponderosa, imho?
The Nant Y Garth pass about 5 miles up the road from the Horseshoe is awesome, if you can get a clear run that is..
