A coworker just relayed this scene to me: Marine Drive, just west of Boundary Road. One Pickup Truck, One Sedan, one mangled mess *under* the sedan, with a back wheel sticking out that she recognized as part of a motorcycle. One large tarp covering something, and there was blood visible on the road. The ambulance arrived, loaded someone, and left, in the time it took her to work through the traffic to go around the scene.
Hope the rider's okay, but it doesn't sound good.
