Ken Burns, in perpetual motion

Where in the world was Ken Burns when his 10-year project, National Parks: America's Best Idea, had its PBS premiere last night? Watching it alone, in his Washington, D.C., hotel room. "I like to watch it when everyone else does," Burns told Current after a National Press Club event today. The energetic documentarian has been making appearances for the project since July 2008, and hasn't been back home to Walpole, N.H., since Aug. 21. That's not all: He's working on half a dozen projects simultaneously. How does he do it? Check out the upcoming Current for an inside look.
