Margherita Taylor is in the Quantock Hills to celebrate the 250th anniversary of the birth of poet Samuel Taylor Coleridge, one of the leading lights of the Romantic movement that took its inspiration from the beauty of the British landscape. The Quantocks were a huge influence on Coleridge, who was an inveterate walker in the area when he was living here in Somerset, and Margherita joins some young people to put quill to paper.Margherita also visits the Somerset Levels, which this year is becoming the UK's second 'super' national nature reserve. She comes face to face with some of the wetlands' tiniest residents and discovers a legend or two. Adam introduces the Irish and English rivals who will do battle in this year's One Man and His Dog competition, while Tom examines the crisis facing pig farmers. And, as we prepare to ramble in aid of BBC Children in Need, we meet remarkable 13-year-old Saul, who refuses to let dwarfism stand in the way of adventure.
