Nathan Vass drives an overnight Metro bus route through Seattle's downtown core. He's also a filmmaker, an artist, and now, an author. On his well-known blog, Nathan tells stories about the people he encounters along his route, and that blog is now a book, called "The Lines That Make Us."

Nathan joins Dave Ross in the studio to tell us some of those stories, and explain why he's stuck around on one of the least popular routes as long as he has.
