So sorry to hear about your loss, Edvard. :(...

Please accept my sincere and heartfelt condolences. Thank you for sharing! I, too, still love and admire my beloved father's memory so much! He was a private pilot, Amateur Radio General Class operator, Master Machinist par excellance, Inspector, and Engineer in the Aerospace Industry, real estate broker, and I forget what else, and played piano and harmonica, and gave us kids an unforgettable life and upbringing, as did my beloved mom. He was born in horse & buggy days and attended a one-room school room in a remote rural county as a boy, who lived to see the age of the atom and home PC.
