Alcatraz

Visitors listen to the new 'Doing Time' audio tour with the Golden Gate Bridge in the background on Alcatraz Island in San Francisco, Tuesday, April 24, 2007. The new audio tour replaces the one that has been in use since 1987. The former Federal penitentiary and visitor destination on San Francisco Bay, has just benefited from a multi-million dollar restoration and renovation that has transformed and improved the way visitors experience the iconic national park. The project has taken place over the past two years and has revamped the way that visitors experience 'The Rock.'
