Although it doesn't look like any more snow this night I am going to err on the side of caution and reschedule the ride away from the 'fellside' road. The ungritted roads around Culgaith are still quite icy in parts and the temperature is unlikely to get above +1C.
So instead of Renwick I propose a largely extempore ride (thank you Nigel for the term) starting at Langwathby at 10.00 and going to the Coral Rooms for late coffee(11.30). By the time we get there (I say we, it may just be me!) we can make up our minds what to do with the rest of the day.
