For me, the journey tells a story – as important as the destination. GPS is just about the destination – its clinical precision can be both boring and utterly wrong. When you can read a map well, you are able to tease out the stories in the landscape. You can see how the new road follows an old riverbed, skirts an iron-age fort, or marches ramrod straight along a Roman road. You can see how a town lies on a raised beach, even though it is now 10 miles inland.
