Hard Times Generation - For some children, socializing and learning in school are being cruelly complicated by homelessness, as Scott Pelley reports from Florida, where school buses now stop at budget motels for children who've lost their homes. Robert Anderson, Daniel Ruetenik and Nicole Young are the producers. Hitchens - Steve Kroft profiles Vanity Fair columnist, author and public intellectual Christopher Hitchens, for whom nothing is off-limits when making his wry and often outrageous observations, including the cancer he is suffering from. Frank Devine is the producer. Spy on the Ice - Bob Simon reports on the latest "spy-cam" techniques used by wildlife filmmakers to show animals - in this case, polar bears - up-close and in a way audiences have never seen them before. Produced by Michael Gavshon.
