Ok, you all were right.. it was bird poop. I noticed there was some on the rear windshield and it is most definitely bird poop. That must have been one huge bird! Never in my life have I seen so much! And it hit with so much force, too! And it was on a route I took almost everyday.. why couldn't it have happened while in my old car, not my brand new car? I guess that's what made me paranoid.
