We speak with acclaimed travel writer Paul Theroux, whose newest book is "Ghost Train to the Eastern Star: On the Tracks of the Great Railway Bazaar." In it, Theroux recounts his experience of retracing a overland journey he made 33 years earlier from England to China. He talks about what appears to have changed and what remains the same in nations like Turkey and India. We also hope to preview tonight's P.O.V. documentary on PBS, a program titled "This Way Up," which talks about a Catholic-run nursing home in East Jerusalem, caught in the crossfire of ethnic tensions there.
