Countryfile - 27/07/2008

John Craven presents a special 20th anniversary edition of Countryfile from Swaledale in Yorkshire - the location of the very first programme. The team look back at the defining moments of the last two decades of Countryfile, from BSE to blue tongue, and reveal what the British public think will be the biggest issue facing the countryside in the next 20 years. Plus, what happened when Michaela Strachan and her fellow presenters swapped their waterproofs for glad rags for an anniversary celebration down on the farm, and Ben Fogle lifts the lid on what goes into making your weekly serving of Countryfile.
