Something actually made me mad at Burning Man this year, for the first time ever. I crashed into an art installation that was not lit. I was driving a 3-wheel bicycle, that was a crowd favorite both day and night, with multiple lights, including 6 black-light spots, a fiber-optic lamp, skulls, roses, vines, and a few blinkies for the wheels. The installation I ran into, consisted of a series of ground lights, very similar to the circle of lights that used to surround the Man in previous years. Within these small lights, there were about 4 or 5 man-hole sized lights, that stuck up about 10" to a foot, made out of metal, or something else quite rigid. Long story short, I was only able to pedal at moderately slow speeds, but apparently had enough inertia to completely smash into this man-hole protuberance, and roll completely over the top of it. In that process, my tire exploded, and the forks of my bike were bent backwards into the frame of the bicycle. I was enraged. It took me 2 hours to get back to camp to find some tools and parts to try and fix the bike where it crashed. Thanks to a close friend, it was accomplished. During those 2 hours, we both had to constantly warn other passers by as they blindly charged through this area oblivious to the danger. Many very close calls. Everyone thanked us as this occurred. I kept my eyes out for any type of authority figures, as I wanted to get the damn installation marked with some kind of light. Finally, I saw a non-art vehicle nearby, and ran to it, thinking it was a cop, but then I realized, they were the people who owned the installation, and were fiddling with their generator. I calmly asked them if this was theirs, and then asked very kindly why it wasn't lit up..?? "Out of gas" was the answer. I then began to tell them that I just wrecked my art-bicycle which I spent countless hours building, and that it was ruined, damaged beyond any type of Playa repair. One "kid" was sorry, the other launched into how it was my fault for running into it. Why wasn't I using a light. That was when I got mad. My bike has so many lights, and this ignoramous didn't even bother to ask about that. I reminded the idiot about the rules of the Playa, concerning any art installations, and told them to use their heads to think about it. I'm practically a professional cyclist, and I was able to withstand my collision with their art, especially since I was on a 3-wheeler. I asked these guys what would happen if a small girl happened to run into the manhole, surely at speeds faster than I was capable. Did they ever stop to think..??? So irresponsible...!! I was infuriated. But what could I do..?? At least one guy got the message, and I'm hoping he feels like shit, for my accident, and for his association with his ignorant partner. I wasn't going to let this ruin my Burn, although it ruined my art installation/transportation. JUST WANTED TO GET THAT OUT... mad at Burning Man, that's ridiculous.
