Sandi is joined by Nick Mayhew Smith who has undertaken a pilgrimage to every "holy place" in England, Scotland and Wales. Nick has compiled a travel guide which not only details where sacred treasures can be found, but also tells you what to expect and ranks them in terms of holiness. Sandi also talks to two Antarctic explorers: Angie Butler loves Antarctica so much she set about recovering the ashes of a forgotten Edwardian Polar explorer and Katie Walter was only seventeen when she made it to base camp at the South Pole, the youngest person ever to walk there. Producer: Laura Northedge.
