I was stationed there as a Navy wife in the nam era. As I recall, no one off base drank whiskey. They all drank aquavit - a licorice tasting white diesel. You would drink it in one small glass next to another larger glass and a pitcher of water to put the fire out. Quite a hangover!
We must get together and compare livers some time. In Iceland and properly chaperoned, of course. Wear a HAZMAT suit.
