S1, E4: Richard Wilson follows the Shell Guides, first published in the 1930s, to explore the British countryside by car. Today, he follows the 1968 guide to Essex and discovers a very different place to the latter day flashy stereotypical image of the county. He visits the historic town of Colchester to see an archaeological dig on the high street, and travels to Mersea Island where he goes oyster fishing on a boat. He then follows the controversial recommendation from the guide.
