This program is a sampler of "Extras" from 3 of our Pittsburgh History Series specials. From RIGHT BESIDE THE RIVER, Nic DiSio from Reyna Foods shows us how he makes tortilla chips in Cadogan, PA, and we talk to folks in California, PA, about an old movie of their town in 1938. Then we share some extra bits from UNDERGROUND PITTSBURGH and WHAT MAKES PITTSBURGH PITTSBURGH? Good fun stuff!
