Ayr to Stewarton

S6, E1: From Ayr, Michael Portillo admires the granite island of Ailsa Craig before getting to grips with the ancient sport of curling, with help from a Scottish world champion. The Ancient Society of Kilwinning Archers invites him to take part in the oldest archery competition in the world. At Barassie, he rides the footplate of a freight train hauling coal on Scotland's oldest railway line. He caps off this leg of his journey in Stewarton.
