The Kelso Ram Sales on the Scottish Borders is one of the largest and oldest ram sales in Europe, with more than 3,500 rams expected to be sold on the day. Charlotte Smith joins local farmer Anne Mair-Chapman as she prepares her prized animals for the big event and meets the farmers buying the all-important ram that will help their flocks flourish over the next year. She also goes behind the scenes to see how this massive market is organised, including moving thousands of sheep around the sale in their very own taxis. Away from Kelso, Charlotte finds out about the official vets who keep key parts of our food supply chain running. Adam Henson is in Cumbria helping shepherdess Katy move her flock down from the fells, and we hear from an inspiring young person who will be joining us on this year's ramble for BBC Children in Need.
