Geoff is off to the Burning Man. He is part of a team that is bringing 300 liters of liquid nitrogen to be used to make ice cream for people who bring them the ingredients. Apparently there is no buying or selling of anything between attendees. Everything is bartered.
Geoff and a couple other guys built a hexayurt to be used as the kitchen for cooking their meals. Each piece is three layers of cardboard with 6-inch fiberglass-reinforced packing tape connecting them. Each wall and roof piece is about 1/2 inch thick. 1-1/2 gallons of wood glue hold the layers together and add strength. It will presumably be a dust-free environment.
Geoff promises lots of photos of his time there.
