The Mission District, San Francisco's oldest neighborhood, is known for its rich Latino culture and the colorful murals lining the alleyways. But in recent years, The Mission has become a symbol of the dramatic economic changes transforming the city. "The Mission Detour," a new interactive audio tour produced by travel startup Detour in collaboration with KQED, addresses these issues in a guided walk down 24th Street where listeners hear narratives that explore both the neighborhood's traditions and the struggles over gentrification and displacement. Join us as we talk with the producers of "The Mission Detour" about creating this "location-aware" experience. We'll also discuss how Detour is expanding its tours to other San Francisco neighborhoods and major cities throughout the world.
