The milk may have been powdered. I never drank it or the chow hall coffee. The guys used to refer to the milk as coming from the “iron cow”. AF coffee was generally pretty bad.
I never made it into Happy Valley either. I didn’t have a car. There were some pretty old cars on the base. They were referred to as “goose-mobiles”. I did get up to Northwest River though. It was primarily a fishing village north east of the base.
Our flight crew used to make quite a bit of money when they flew to isolated bases. They would load up on fresh bread, eggs, milk and sell it on base. An underground economy.
