After nearly 50 years, Iowa Public Radio’s Rick Fredericksen is hanging up his sound kit. After getting his start with the American Forces Vietnam Network in the late 1960s as a young marine, he’s won numerous awards and has reported on some of the biggest stories of the 20th century. During this hour of Talk of Iowa, host Charity Nebbe talks with Fredericksen about the Peabody Award he won with CBS News reporting on the Tiananmen Square in 1989 to the time he met Robin Williams when Williams was in Vietnam researching his role for the movie “Good Morning Vietnam.”
