Let me be the first non-asshole eplayan to welcome you to our friendly discussion board! Welcome!
I (and possibly some other burners) love it when mainstream media pick up on some of the individual elements that make Burning Man so special. It shows a deeper appreciation for the depth and richness of what goes on at BM, as opposed to mainstream media that simply report on the event as a giant freakshow. One of the coolest and central elements at Burning Man is the awesome diversity and number of silly, clever, stupid, scary, dangerous, fuzzy, efficient and beautiful vehicles you see plying the playa.
Good luck with your project, and thanks for spreading around an element of Burning Man that might strike some gearheads as interesting and generate some respect for the event and its population among people who might otherwise write the whole thing off as hippie drug pagan bullshit.
Please send the results to the BM website or post it here so we all can see it later.
