Never ride in the back of a pick-up truck

You might have heard about the tragedy on that bridge that goes across Percy Priest Lake. There was two fellas in the cab of a pick-up truck, two of their friends were riding in the back, and they went off the bridge into the water. The two fellas in the cab rolled down the windows and escaped to safety, but the two fellas in the back of the truck drowned. They figure it was because they couldn't get the tailgate down.
