For this Martin Luther King Jr. Holiday edition of Ozarks, we hear a series of conversations regarding the various aspects of service. We’ll hear from the organizers of an annual half marathon that supports programs and services in one local small town, we’ll hear how the Salvation Army provides services to some of the most vulnerable residents of northwest Arkansas, and we’ll hear how a department at the University of Arkansas helps train students to embody the service mindset as they prepare to enter the working world.
