This week on Valley Edition we hear how law enforcement agencies are helping their officers and deputies cope with the mental strain of the job. We also learn why activity tracking software is helping elephants at the Fresno Chaffee Zoo and across the country attain better health and welfare. Later in the show we talk local political races in Fresno and Bakersfield with Nicole Parra and Jim Verros; plus learn about a new book on the history of Kerman from Paul Betancourt. We close the show with a talk about the events coming up in Kern County for the One Book, One Bakersfield, One Kern event, which this year is focused on "The Big Thirst."
