In Cedar Grove, Wisconsin, there is an annual Holland Fest, complete with klompen dancing, Dutch costume, oliebollen - a kind of pastry like a giant doughnut hole, and worstebroodjes - like pigs in a blanket. I think there is a band, too, that plays "traditional" music. But its been over 150 years since the Dutch settlers came over from the Netherlands, so God only knows how authentic any of this is.
