Personally, I see Afrikaburn as a gathering for mainly pretentious rich peeps to escape the city and pretend to live without money for a while and be all arty farty. It's definitely not carbon neutral, think about all the fuel used to fell the wood, craft it and then transport it 100's of Kms to the venue only to get burnt. With all the money and time pumped into it one could do amazing upliftment projects and still throw a mad jol without all the pretentious burning.
Same goes for most tranceys these days, they just not what they once were. Woodstock still hasn't been beaten and never will be.
