Gone to Look for America

So Art Garfunkel once did a walk across America:

"Somewhere around '84, I left my New York apartment, cut across Central Park, and went past my alma mater Columbia University, across the George Washington Bridge and I was in New Jersey. Most of the time I was alone with my Sony Walkman and my notebook in my pocket. .... Over forty more excursions, about three a year, taking about twelve years, I crossed the entire United States."

Now he's doing a Eurowalk, but hasn't reported any progress lately.
