My sympathy goes out to the Heister family. My dad Carl enjoyed working with Bob at the Power Plant for many years. He was one of the "good ol' boys." My mom always loved our outings to pick up pecans at Bob & Sue's grove when my sisters & I were young - we had lots of happy memories of those days. In fact, we were just reminiscing about that recently. Your family will be in my thoughts and prayers today and in the days ahead. May God bless you with many fond memories.
