The photo in the above link doesn't do justice to the steepness of the hill. To the left of the camera the road is essentially level and the part of the hill shown is about 1 in 5, steepening further down. Approaching it in a car the road seems to go over the edge of a cliff. I think the reason is due to the use of a fairly wide-angle lens, which always has this effect. Using a long lens you can make even a railway gradient look insurmountable.
[Rosie] Thanks goodness. I love the Co-op, especially since they revamped themselves. Their 'Indian Prince' tea makes a wonderful, ordinary cuppa and is as good as anything Twinings makes.
