dw, I lived in Rapid City for 2 and 1/2 years and they have a replica of a old Norwegian church. My deceased grand father had to see it when he came out and it was the highlight of his trip. He belonged to a Norwegian church in Minneapolis and had heard all about it. What I remember is it had a little open window on the side so lepers could watch the service from outside.
