Look to the skies above the National Mall starting at around 1:30 PM on Saturday. It's not a bird, or a plane, it's author William Joyce! See him on a terrestrial break from his sublunary journey at the 2011 National Book Festival in Washington, DC this weekend. Have a copy of The Man In The Moon signed and enjoy a lovely autumn afternoon at this event sponsored by the Library of Congress. A map of the pavilion layout can be downloaded here.
