Overview: There's a palpable sense of urgency in the air in the Dales as lambing season starts for the hill farming Dawson family, with the arrival of forty lambs per day. In Swaledale, at Britain's highest pub, the Tan Hill Inn, Vanessa and Nigel have survived the winter months but must now decide if running one of the remotest hostelries in Britain is really for them. Also, Ribblesdale primary, a 300-year-old village school in Horton, faces closure. And gamekeeper David Hutchinson and his team begin preparing the fells and woods for the shooting season.
