We had a Norwegian exchange student in 1978-79. The Christmas after she went home, Eddie and I, along with our son and daughter, were invited to spend Christmas with Grete's family. Her dad was an army general in command of all of north Norway. That put us north of the Arctic Circle for the holiday. We participated in their traditions at home, church, and on the army base. Since her dad had access to the King of Norway's cabin when the king wasn't there, that was where we slept. It was an unforgettable Christmas with a wonderful family.
To make it even more unusual, it all took place where it was dark except for two hours of twilight each day.
