If you are in the Washington, DC area, block off Thursday night, March 20.  Details are still pending, but I’ll be part of a great event at the Smithsonian’s National Museum of American History (1400 Constitution Avenue, in the Warner Bros. Theater): a panel discussion about the history of the natural foods movement, moderated by Smithsonian Food Curator Paula Johnson, and also featuring Honest Tea President and TeaEO Seth Goldman.  Tickets will be $15.
