I was preparing for a photo essay I was working on, and working on handling while I took photos over my shoulder. Long story short, I should have known that would not work and I am damn luck both I and the camera still work. I went over my handlebars and landed on my several thousand dollar SLR camera. All that broke was the UV filter ($5-$10). It still needs to be repaired though, the metal ring of what once was the filter got jammed into the treading on the lens. I do have a small scar still on my knuckle from it being dragged along the roadway.
After I crashed two cars drove past me without offering assistance, and once skateboarder went past me on the other side of the road looking at me while I struggled to get up.
That was perhaps the stupidest thing I have ever done.
