When my Norwegian FIL visited Westby, he was disappointed because they spoke an archaic version of his language. He had been hoping to find folks with whom he could converse in Norwegian. We heard the same complaint from the Norwegian ski-jumpers at the Snowflake Festival.
OTOH, the food can be authentic.

It’s called Danish...most who emigrated were still under Danish rule at the time and spoke it.
lutefisk and lefse hmmmmm yum yum. Well....maybe the lefse with butter on it.
