High-wire artist plans series of U.S. walks

Philippe Petit is planning a series of high-wire walks next fall around the United States.

The 59-year-old says they'll include midtown Manhattan and will promote literacy. He's keeping mum about other details.

Secrecy also preceded Petit's 1974 walk between the World Trade Center towers. A documentary about it, "Man on Wire," won an Oscar this year.
