I wondered how they moved the huge beams, but seeing the man in the back holding a string or chain tied like a toy made me laugh. As if he could do anything if that thing got out of control.

I don't think truck drivers who open their decks and crash into overpasses are idiots. I was driving a flat deck truck with a 12' tilt bed. I looked at a restaurant I was driving and saw a boss pointing at my truck with a confused expression. Not knowing what I was looking at, I looked in the rear view mirror and only saw that my deck was fully elevated. I immediately dropped the deck with a loud thud. My deck-lifting arm had somehow gotten itself into a raising position.
