To mark the centenary of the start of World War I, we'll hear how the British are remembering the Great War, and what's afoot in London this year, where WWI sites, events, and memorials make good on the British promise to "never forget." Then we'll visit the areas of the former Yugoslavia, where the war started, to hear what it's like today. We'll also get a taste of the best regional foods you can enjoy on a road trip across the Southern US, from "Road Food" specialists Jane and Michael Stern.
