Car vs. Deer

What in the wide, wide world of sports is a-goin' on here? Champ Car driver Cristiano da Matta has undergone surgery for a blood clot near his brain, after his car collided with a deer during testing at a circuit in Neenah, Wisconsin. His car hit a deer on a race track?!? Holy crap! First off, that has to be a shock to the system. Second, you would think there would be precautions against deer getting on the track at Road America because the course is surrounded by heavy woods, and well, THERE ARE CARS ON THE TRACK GOING REALLY, REALLY FAST! Third, there has to be video out there somewhere. Please, someone find it ASAP.
