A public television producer turns to eBay to raise money for his film ... This is Future Tense from American Public Media. I'm Jon Gordon. Unable to find corporate underwriters, Chuck Strinz says he went deeply in debt making his film "Back on the Mississippi." The film tells stories of people and places along the Mississippi River, from St. Paul to the Quad Cities of Illinois and Iowa, and will air later this year on several public television stations across the country. It's already been shown on stations in Minnesota and Iowa.
