This week on Valley Edition we’ll learn why Porterville is becoming one of the leading communities in the state when it comes to making the switch to electric buses. We’ll also talk with the author of a new biography on the life of Fresno’s Kirk Kerkorian. We’ll learn how his early life in the valley helped shape his career as a billionaire dealmaker who conquered Hollywood, Las Vegas and the auto industry. FM89’s Kerry Klein joins us to recap the valley’s winter air pollution season, and she’ll give us a preview of Wednesday night’s public forum on air quality at the KVPR broadcast center in Clovis. We’ll also get an update on a new bill in the legislature that would ban willful defiance suspensions in grades k-12, and we’ll take a look at the changes coming to high-speed rail following the release of the rail authority’s new business plan.
