Two thoughts. First: I most certainly remember these visits at KAGC (Allegheny County, Pittsburgh, PA) “Back then it was routine for flight instructors to bring students inside to meet the voices at the other end of the airwaves. These invaluable experiences…” The folks behind the counter provided friendly, insightful information (in my case probably lifesaving) before my flights. Second thought: Had not thought about the ring issue for years. When I had a need to wear a ring I always seemed to get it caught on something, causing bleeding and pain. Thank you for reminding me of those moments! (Not.)
