I drove over this minutes after it happened, headed south on N main st bridge, it was under the bridge on Howard. Saw a burgundy harley on its side, several police and ambulances at the scene. It had rained VERY hard about 15 minutes before that, and its a tight corner there, under a bridge, so that may have contributed. Of course, I can only imagine they were attired in standard harley gear, IE as little as possible.
