Marcia Franklin interviews Greg Smith, the protagonist of the "Independent Lens" film "On a Roll." Smith has muscular dystrophy and cannot walk, but hasn't let that stop him from using his other abilities to motivate both disabled and able-bodied people. For years, he hosted a radio show called "On a Roll," which looked at disability issues. The program has evolved into "The Strength Coach," in which Smith interviews inspiring people from all walks of life.
Smith talks with Franklin about his life and aspirations, what it was like to film the documentary and disability issues that concern him.
