Elder son Merle, back from Burning Man 2012, tells of a brilliant rule: "If you notice something on the ground, then it's yours!" That is, if you see a bit of litter then your duty is to pick it up and put it in its proper place. If you find something worth keeping then consider it a "playa gift", from the desert plain to you. Feel free to give it to someone else or hang on to it. Smart psychology: the result is a much cleaner festival site and a hugely enhanced sense of personal responsibility. Works for me too, walking to/from the Metro in the morning and elsewhere.
