Darryl Thompson

This is the 1st time I have sat down and thought about why I do what I do and thinking back to a very young age.

The fact is that even as a young boy I loved working in the family garden when we lived in Atlanta Georgia. I worked with my parents picking peas, beans, corn, pulling the weeds etc. This coupled with the fact that every morning I saw my Dad wake up and put on a suit and tie which now I call the “Money suit” even though I enjoy dressing up at times as I have grown older.

This love for the outdoors, growing plants and not having to wear a suit in the summers was deepen when I would go to Texas to my grandparents’ home town. I was very lucky and blessed all my grandparents lived in the same town. I was also blessed that both of my grandfathers had served in World war II and come home to have my parents. So, I could visit them in the summer months when school was out and they both have cattle farms, horses and businesses of sort that I helped with. So, when I was ten years old I learned how to drive the tractors and haul hay. It was awesome because they no longer had the square bails that I could not lift. I was learned how to drive the tractor after much persuasion on my part to my Mom’s dad. After this I learned from my Dad’s Dad how to run and drive a backhoe as he had a business hauling dirt and digging septic lines for new homes in Northeast Texas.
