Pure Stupidity on my part. I use Battery Tenders, so the wires don't get smashed, I prop the hood up with a hood block. Took the Battery tender off over the weekend a while back. Did not put it back on, dropped the hood back down onto the hood prop. Decided mid week to take the car out for a ride, forgot I had not secured the hood. We did great around town, did not notice the hood raised at all from the drivers seat. When I hit the country roads and hit 55 to 60 MPH, the hood flew up and back. Scary as heck. Took out the hood and the windshield. I now have a check list I go through before I get one of my cars out for a drive.
