My parents divorced when I was three years old. My father is a rancher and so was my maternal grandfather. My maternal grandmother insisted that my grandfather sell his land, cattle and everything else and move to the city. Apparently, my mother attempted the same with my father who unlike my grandfather refused. Divorce followed shortly after.
We moved to San Antonio shortly after the divorce. I spent summers and winter breaks at my dad's place growing up. As a kid going from an actual city to BFE south east Texas was a beating. In the Summer's, I was assigned to work with my dad's dad so we would hop into his Ford F100 from the 1950s and work. Horrible.
My mom married my step-dad when I was eight years old. He was an engineer and a colonel in the USAF. After retirement from the USAF he became a professor at St. Mary's University as an engineering professor.
I feel like I am a combination of my step-dad and father. I pursued STEM and other intellectual pursuits because of my step-dad. My eldest son is an officer in the USAF and I wish my step-dad was alive to have seen his commission. There are a lot of things my dad has also imprinted on me too.
I'd say I am definitely the product of two dads. Looking back on how my kids were raised, academics, sports and competition were heavily emphasized. That was my step-dad. But my kids all had their own horses and were expected to work our land and service tractors, trucks, etc... that was my dad.
