Today, we hear from a radical change maker- Tim de Christopher. He's celebrated as a monkey wrencher for disrupting a federal auction for oil leases. He's also in prison now, convicted of two felonies for that federal crime. Our contributor Alex Chadwick shares a journey with Tim, in the months before he goes to prison and together they explore the repercussions of change as they raft a river in Utah. This is a part of the series “Searching for Change”.
