I learned with a Chevy 2 ton truck. First you loaded it with bales of hay, then grandpa drove it slowly to the feed pasture, then when grandpa would put it in compound then had me idle around jolted by the frozen cow pies while he tossed the hay off the back. Once I mastered that I got to drive it to and from the hay stacks! If you turn to fast hay would fall off and then you had to reload it, so that lesson was easy to remember.
Eventually I had to take drivers ed to get a license at 15. Gore movies, 60's Chevy, Shop teacher who was a very calm guy. Small town with no traffic, 65-70 on highways that had NO SPEED LIMIT. Most of the guys had drove before, just a formality. Mr Banks the shop teacher was a good guy. Unfortunately he and his wife were killed in a head on collision on a 2 lane highway. It was not his fault.
Montana in those days was a dangerous place to drive. All 2 lane highways, no speed limit, lots of narrow bridges, curves, drunk drivers and even a few drunk HPs. Oh, yea, then there is the winter weather.
