bugger, got half way and finger trouble dropped my thread !
a.t. was spot on about the BiB - Volvo and Subaru on the Yorkshire section of the A65, Clapham to Skipton and also Inglton to Hawes road.
There is often a mobile van camera on the other (Lancashire) end of the A65 between Kirkby and junction 36 of the M6. Also a gentleman on a bike around the Bull Beck cafe stop in Caton, and a standing plod in the car park of the Truck yard (as you come out of Caton, just as you start to wind up for a long straight stretch - right at the national speed limit sign !)
Not booking as i live down the road, but will hope to drop in and join for a ride or two.
