Patti Miller was a classmate of mine, a member of the famous JHS class of '61. Another classmate, Jayne Owen Tomes sent me the info. I am sure you can see the program in Iowa but not sure about other states at least not yet. The info about show times etc. can be found on this site:
Program Description: In the summer of 1964, hundreds of predominantly white college students answered the call from Civil Rights leaders to volunteer for Freedom Summer. They joined with voter registration efforts, taught in freedom schools and worked in community centers in towns throughout racially segregated Mississippi. Return to Freedom Summer gives first-hand accounts of the experiences of 5 Iowa natives who, though personally unfamiliar with racial issues, felt compelled to volunteer that summer. Viewers will hear their stories as they share their motivations, fears, triumphs and life-altering events that took place during that historic summer 50 years ago.
