Jenny and Annie learn about the geology of the Scottish Lowlands, and travel as a wee grain of sand through half a billion years of geologic movement, ending up within the River Tweed.  In more recent history, we unravel Arthurian legends to explore the story of Merlin, the wizard of the wilds. A real cornucopia of Celtic mythologies and folklore.  This episode is sponsored by Scotland Shop.
