This week, we'll hear about the sheep and lambs that dot the hills of rural Britain from an accomplished breeder who welcomes tourists to his sheep farm in rural Wales. Rick discovers a few new tricks they use to train the dogs that herd the flocks. We'll also learn about Welsh Christmas traditions, which include a lot of singing and wassailing.
