I recently ran over a dead deer. It was previously hit by something, and was clearly down for the count, halfway into the road. Unfortunately for me, there was some serious construction going on and I had absolutely no way of swerving to avoid it. It was either hit a tree, or hit a construction barricade wall. I had some blood spatter that kicked up on my fender, and something in my tire.

Nothing a good powerwashing didn't fix.
