KPCC will debut "Off-Ramp" Saturday at noon and run it biweekly until October, when it goes weekly. John Rabe, a reporter at the station who is a veteran of public radio, hosts. Queena Kim, late of Pacific Drift, produces and reports. They call "Off-Ramp" a show about Southern California news, art, culture and life. On the first show, they go for a ride with Times motorcycle beat columnist Susan Carpenter, speak with photographer Catherine Opie and political commentator Marc Haefele, and visit pit 91 at the La Brea Tar Pits. Nothing on the KPCC website. (* They got the site up late Friday: Link)
