It's in the back holding on for dear life alongside the bladeWere's the Ford truck pulling this rig, down the road.
Now this looks like what i drilled withThis is what an oil rig looked like in my day. The platform was modular and was assembled and dis-assembled at every site. Sometimes if the move was short, they would haul the Derrick in one piece, one truck in the front and one at the rear, backing up. Some were two drill stems tall and some were three. Note the platform at the top, a derrick hand worked there (Crows Nest). Talk about cold in the winter time.
