I had a bit of the opposite happen -- when that gust of wind came along, my hood would stretch open much past its intended angle. This can lead to major chips on the paint edge, as well as high blood pressure when it happens. As far as I can tell, the earliest cars did not have a hood-strap to prevent this. I finally decided that there are enough things wrong with my car to keep me out of the concours event -- and I broke with originality and added the strap. A few dollars and a couple small holes later -- no more worry of the hood going vertical on me. I guess I still have to worry about the head banger though...
