When the Keystone Dam west of Tulsa was built, they brought in the turbine to generate electricity on a monster depressed flat-car, then loaded it onto two "low-boy" semi-trailers (8 axles each, I think) with one tractor driving forward and the other IN REVERSE at thundering 3MPH. Then did the same thing with the generator. My Dad and I tried to get where we could phototgraph either move, but there was 7-8 miles of solid bumper-to bumper traffic on the road that's now underwater, and neither of us had the idea of hiking 10 miles of rough up and down woods to hope to find a place to get a picture, especially since both moves took place when there had been rain to heavy thunderstorms.
