We commemorate the early days of the Peace Corps with travel writer Paul Theroux, who served as a teacher in Africa in 1963. He'll also share his perspective on when foreign aid does and does not work. Also, Seth Kugel shares highlights from his inaugural trip as the Frugal Traveler for the New York Times when he spent 13 weeks on a budget to see the sights from Brazil to New York by way of Bolivia, Colombia, Guatemala and Nicaragua.For more information on Travel with Rick Steves - including episode descriptions, program archives and related details - visit www.ricksteves.com.
