Vikings in the Attic

In Search of Nordic America, by Eric Dregni.
Eric Dregni tracks down and explores the significant-and quite often bizarre-historic sites, tales, and traditions of Scandinavia's peculiar colony in the Midwest. For all the tales his grandparents told him, he quickly discovers quite a few they neglected to mention. In the end, he proves by example why generations of Scandinavian Americans have come to love and cherish these tales and traditions so dearly.
