We will be congregating between 3:00 and 3:30 in the Kogod Courtyard of the National Portrait Gallery (8th and F Sts or 8th and G Sts NW, go straight past the information desk from either entrance), and heading out after that to look at exhibits. Those present will decide on museums to visit (possibly including the National Portrait Gallery itself) and inform anyone joining belatedly of location and direction of travel via the lesswrong-dc Google Group.
