Author Talk: "The Limit" by Michael Cannell

Jeff Glor talks to Michael Cannell about his book, "The Limit: Life and Death on the 1961 Grand Prix Circuit," the story of Phil Hill, the first American-born driver to win the Grand Prix - in one of the deadliest contests in the race's history. Cannell also writes about the men who surrounded Hill - like his teammate and rival, Count Wolfgang Von Trips (nicknamed "Count Von Crash"), and the reclusive and difficult head of the Ferrari racing empire, Enzo Ferrari.
