The world has fewer nuclear weapons than it once did. But it would only take one to cause death and destruction on a massive scale.
David and Anne Hall of the Ground Zero Center for Nonviolent Action spent the last three decades working to rid the world of nukes... while more countries have built the weapons.
They appear at events in Eugene this weekend, welcomed to town by Oregon Women's Action for New Directions.
David Hall visits to talk about his work and the results of his efforts.
