Devon highways and byways

This, believe it or not, is a main road, the A399 between South Molton and Ilfracombe. It is misty and I'm driving carefully when out of the mist I see a tractor, followed by this herd of sheep, followed by a collie dog and another tractor ensuring they all arrive at their destination!  
What a treat and so glad I had my camera in the back of the car and had time to jump out and snatch one shot!
