I was in my car Christmas night returning home via interstate and out of nowhere an owl or hawk smashed into my windshield. No damage to the car, but I'm sure the bird wasn't feeling too well. Friend of mine told me once he was running down the interstate on his bike and the same thing happened. I believe he was able to hold on. As hard as the bird hit my windshield it seems like it would knock you right off the seat. Anyone had this experience? I saw it right before it hit the windshield, so you'd probably have just enough time to tighten up and duck.
