A plumbline will always find the vertical axis pointing to the center of gravity, ensuring everything is right, justified, and centered.  ​ Pulling from a library of more than 3,000 shows from his storied career in broadcasting, Shelley's Plumbline leads us in a search for the truth, opening the channels of communication and understanding on tough social topics that are as relevant today as they were 40 years ago.   Join us as we explore the past, compare it to today, and craft a better future.
