Jack will be missed by a large number of people. He was someone I respected and enjoyed working with over several decades. To me, he epitomized a quintessential Texan for his generation: friendly, strong, independent, and always desirous of doing the right thing and choosing the correct path. I feel fortunate that our paths crossed and intertwined. He had both a very strong work ethic and loving care for family and friends. While we had a business relationship it was deeper than that, it was a personal relationship. A few years ago my wife and I took Jack up on his offer to see his orchids at their peak in May. He and Laura were very gracious hosts to us on a Saturday afternoon as they provided information and answered our questions as we toured the greenhouses and the first floor of their house. It was an enjoyable and memorable experience. I wish the family well as they go through the time of mourning. May Jack's memory be a blessing to us all.
