Thanks for your message - I contacted Son's of Norway and apparently I still have a record of membership. All I have to do is pay dues! They have an online class. But she also recommended the Norwegian Lutheran Memorial Church for classes. They had one start this week but I'm not ready to take that long drive right now - another one starts in September that I may consider. I also signed up for Norwegian 101 - word a day email. It's amazing how much I actually remember.
We also learned a Norwegian Christmas song that I have the words for somewhere around here. And we always prayed a Norwegian prayer that I can still recite all the way through.
