Come out of the Dover ferry terminal, go up up the A2, Jubilee Way. That is some hill; it is steep; it even has escape routes. You come to the Duke of York’s roundabout.
That got me thinking was this the hill the Grand Old Duke of York marched up and down? It’s near Dover Castle after all.
Alas, no. http://en.wikipedia.org/wiki/The_Grand_Old_Duke_of_York. But it was a nice idea.
