I left Adak in late 1981 and remember well the three you mentioned. Robin, Bob and I were at Kef together and I learned so much from them. Gary Peterson was really great and always had a positive attitude. Unfortunately both he and Bob are no longer with us.
It's really depressing to see Adak now. The buildings are in a sad state and nothing is really happening there. That's too bad as it was a great duty station.
