Oxnop Common going north from Askrigg and then Butter Tubs Pass going south (the "hard" side) from Mukor. And to extend the pleasure a crossing of Widdale Fell from Garsdale Head and Station (of the S&C) down to Dent Station before turning north.

Passed some 25% road signs on my way to 39 miles and 4800 feet. The road south of Garsdale Head is quite vicious but the road sign by the station eschews a gradient and just warns that the road climbs to 1762 feet and "can be dangerous in winter".

Yes I imagine it can.
