This weekend I’ll be in lovely Williamsburg, VA on the campus of William & Mary.  The occasion is the 2010 Int’l Mercury Expo, subtitled ‘A hazard without borders.’  I’m scheduled to speak to the acting students (poor things) at lunch on Saturday, and that evening I’ll be talking to student and the public on social activism.  The schedule is here, the school calendar page here, and the Facebook page for the event is here.
