First, Bob talks with travel writer Rick Steves. For the past 30 years, Steves has advocated for thoughtful and informed traveling through his PBS series, his radio show, and of course his best selling travel guide books. His book, Travel As a Political Act, is about why we travel and how being a good traveler creates positive ties with the citizens of other nations.
Then, Bob talks to Keith Bellows, editor-in-chief of National Geographic Traveler magazine. Bellows and his staff have compiled a list of the 500 greatest trips the world has to offer. It encompasses every continent and every possible mode of transportation, including the world's top 10 elevator rides. The book Journeys of a Lifetime: 500 of the World's Greatest Trips is published by the National Geographic Society. [Broadcast Date: August 23, 2010]
