Scene from a Motorcycle Accident at Market & Eureka

A nasty spill took place this morning at the intersection of Market and Eureka streets. SFist reader John M. sent us this image from the scene. He guesses that it was "a left onto Eureka gone bad," going on to say that the rider was "not happy and very fetal." Ack.

Obviously, we hope he or she is OK. Anybody else see what went down? So to speak.
