At Burning Man 2005 (Amnesia & 6:30) and 2006 (Esplanade & 9:00) we screened nightime video and invited dialog.
In 2007 we were at 7:30 near the Esplanade. The space was not as practical for nightime video (though we did build a mobile projection system), but we added daytime interactive events (films & lectures) and a social space.
In 2008 we were on the Esplanade near 4:00. This was the first year we brought the Ask-a-Vegan booth, which was very popular. We also displayed a series of photographs called "I am Someone."
In 2009 we were at Biology & 5:30. We found that we had much more unstructured interaction with passersby this year, with many people dropping in to ask questions or visit with us. We added a food giveaway, reaching about 600 people with vegan hot dogs & sausages, and brought a new series of much larger photographs, called "Being Somebody."
In 2010 we were on Cairo near 5:30. We had less foot traffic than in previous years, but made up for it with large-scale food-giveaways.
In 2011 we were at 4:30 and Coming Out. This was a busy location; we had lots of visitors to the Ask-a-Vegan booth as well as most of the other activities we've done in previous years. At this point our camp has also become a favored hang-out spot for vegan and vegetarian burners, and we had snacks and a fire until the wee hours every night.
