Attendees to a recent meeting at a small country church on the border of Minnesota and South Dakota found armed guards at the church entrance. Then someone saw an AR-15, prompting a visit by the sheriff. It's the latest development in a battle for the soul of Singsaas Church near Astoria, South Dakota. The conflict pits a divisive new pastor and his growing nondenominational congregation, who revived the old church, and many descendants of the church's old families, worried about the future of a pioneer legacy.
