Join Plodcast host Fergus and countryside writer Professor Fiona Stafford in the curious hilltop village of Brill to learn how to find hidden history in the landscape around you. Fiona's new book, Time and Tide (John Murray) is a series of fascinating adventures looking at how our countryside is transformed over time - and how quickly things are forgotten.

Contact the Plodcast team and send your sound recordings of the countryside to: editor@countryfile.com.

If your letter, email or message is read out on the show, you could WIN a Plodcast Postbag prize of a wildlife- or countryside-themed book chosen by the team.
