Randy Welcome to our forum.
I had a friend in the Navy on Adak in the 1970's and he drove his van around in circles on his time off. He about went stir crazy and tried fishing in a boat and got lost at sea. They found him okay. He was glad to get out of there. I saw some pictures of part of the base a few years back and it was almost abandoned.
