Roadside Revelations

Stories from BBC correspondents and writers around the world, introduced by Pascale Harter. In this edition it's all about lessons learned while on the road, as Karen Allen reflects on American-Kenyan relations during President Obama's visit; Mike Wooldridge looks back at his decades of work as a BBC correspondent, working everywhere from Ethiopia to Afghanistan on stories ranging from devastating famines to the revival of local cultures; Antonia Quirke finds that unlike the gloom found in much of the rest of Greece, the mood on the island of Hydra is still defiant amid economic crisis; and Bob Walker tramps hundreds of kilometres along one of the world's newest Catholic pilgrimage routes, the Caminho da Fe in Minhas Gerais state, southeastern Brazil.
