Program 733: Walls Around the World; Tourism in Spain; Tecumseh

A Jerusalem-raised Palestinian tour operator explains how he works to reconcile divided communities — in his home country, and far beyond. Then two Spanish tour guides consider what makes their country one of the world's most popular destinations among tourists, and what they want visitors to experience there. And a historian discusses the legacy of Shawnee chief Tecumseh, and why, in the early years of the US, he was so admired even by the settlers he opposed.
