I was on my way to an appointment and saw the remains of a purple Hayabusa in the opposite kane of I-70 heading towards Florissant Missouri. Almost the only thing left to distinguish it was the hump and tail light. the car that was involved in the accident was smashed all the way down the drivers side. The bike looked as though it went down hard and my have flipped a few times. Have not heard anything on the radio or news yet. Was around 4 to 5 when I drove by. Did not see the rider anywhere, probably air vac and on way to hospital if he is alive. Hope the guy is alive and recovers. Looked really nasty. Makes you think when you see something like that.
