Leaving on a Penske truck...

So my daughter is moving home this weekend. I am heading out with a Penske rental truck. I am only hoping she has found help or its going to be a very long day. Anyway, I used Google Maps to check out some roads and various routes to take. I was looking at highway 55 and thought I would try "street view". It was pretty cool, showing me the type and condition of the road. As panned around though something caught my eye. I have no idea what it is. I wonder what it could be? A dead duck? some sort of weird shadow. I haven't a clue. But here's the link if you want check it out:
