It's been nine long months since Derek took his last breath on this earth. He had many passions that stemmed from his nature, but they grew exponentially after he was diagnosed with brain cancer in 2011. One such excitement was the thrill he got from working as an engineer at Precision Planting. He spent many hours in the hospital and in waiting rooms writing this book, intended to pass on the knowledge he gained during his career to anyone who is interested, but especially to those he cared about. We have taken his rough draft and tried to present it in the way Derek would have if he had been given the time to polish it. All proceeds from the sale of Derek's book will go to the Sauder Children's Fund for the benefit of his four children.
