There are enough festivals in most towns in the US and Canada to keep us happy all year long. So, do we pack our wings and stilts, take our clothes off and paint our bum blue, try unidentifiable street food and circus skills, crowd-surf to the front and launch ourself into space from a giant catapult? And lose it, just for a few days? Will this be the year we finally make it to Burning Man? Not likely!
