I get a little jumpy when a rock hits my windshield I can only imagine how freaked out I would have been if this happened to me. In Massachusetts, a couple were driving down the highway when an ax came flying through the windshield and stuck into the dashboard. It looked like a scene from one of those Final Destination movies. The owner of the ax said he forgot it on the hood. I have forgot my soda on the hood but that isn't going to take someones head off. Make sure your load in fastened before you hit the road...and watch out for flying axes.
