The broadcaster takes in the delights of the Lancaster Canal, setting out from Tewitfield. As he meanders down the waterway, John cannot resist visiting Carnforth railway station, where he re-enacts his favourite scene from the classic film Brief Encounter, some of which was filmed there.

Later, he heads south to Garstang, famous for its cheeses, and finally on towards Preston.
