I learned to drive in a similar 1946 Ford pickup truck when I was 12. For a few years, a coupe of times each summer I would spend a few days a hundred or so miles NE of Dallas, in Pittsburg, Texas. I helped an old fellow tend his small herd of cattle, pigs and cucumbers on a small farm that he leased about seven miles from town. At first, I drove only in the pastures, then on the sandy roads, then finally on the rural two lane highway to his house at the outskirts of the small town. It was a great learning experience. His truck was pretty worn and it’s top speed was about 37 mph before the front end vibrated too much.
