Honestly I don't know. This morning in taking my son to school, I had to stop at a 4-way intersection. As I took off from it, we passed a couple of kids that were on the sidewalk making their way to the elementary school. One was a girl, probably 10, and a boy, probably 7. The boy heard my car as we left the 4-way, stopped, turned, and stared. As we got closer to him you could see the 'look' on his face that a car guy has when the right type of car crosses their path. He is a future car guy. I guess that's the way it was for me too. It was just the thing I gravitated toward at a young age. In 1969 I saw a brand new, red Mustang Mach I sitting in the church parking lot. After church I HAD to go look at it. I didn't know why, I just HAD to. It's been that way ever since. My Dad was very mechanical, but he never had a muscle or sports car, so I didn't get it from him really. But he did teach me how to work on engines. Through my own reading and comprehending I expounded on the mechanical understanding and when he had me rebuild his truck engines, I made them meaner.
