 Nicholas Kristof is our guest on Travel with Rick Steves. In his memoir, Chasing Hope, Nick reveals why he's an optimist, despite all he's seen in his work reporting from the world's hot spots. Nick's joining us from his family farm in Oregon's Willamette Valley, where he started out as editor of his high school newspaper. Today, you'll see his op-ed columns twice a week in the New York Times. You can find out more about Nick's family farm, where they make cider and wine, at kristoffarms.com.
