I went down when I hit an invisible slick chemical spill on a concrete on-ramp loop onto an interstate in Jackson, MS and slid for awhile. Bike took a lot more damage than I did. Last I saw of it it was in mid-air tumbling. However all it needed was a new handlebar, repair of a large dent in the tank, and probably a small item or two I don't remember. 1979 Suzuki GS850. I got a bit of road rash. I don't qualify to be on the list here.
