Pete Hamill and Nora Ephron reminisce about their days at the New York Post in the 1960s, and talk about how journalism has changed since. Hamill, whose latest novel is "North River," is a distinguished writer in residence at NYU's Arthur L. Carter Journalism Institute; Ephron is the author of "I Feel Bad About My Neck," "Sleepless in Seattle," and "When Harry Met Sally," among many other works.
