I'm leaning more and more toward a deer.
We shall see.
That makes sense. I once hit a deer on a dark deserted road the night before Thanksgiving. Because I didn't see it until I hit it, I didn't have time to even brake. In my case, my hood flew up and broke my windshield and I had a most difficult time stopping since I couldn't see. But had I seen the animal before I hit, it would have been easy to brake and swerve and then run off the road.
