I remember growing up in Garden City and every summer he would put on the Wild West shows! My family loves to go and watch the whole day and enjoy the amazing food! We lived just down the road and I frequently visited the animals he had even after the shows were no longer put on. He was a great man and I’m saddened by the loss of him. Everyone is in my thoughts and prayers.
