The Maudes live on a farm in South Dakota, where they raise 250 cattle and 40 sows and have diversified crops. Twenty-five acres touch the Buffalo Gap National Grasslands, and when they were told by the Forest Service they were blocking access on those 25 acres that were government property, the Maudes believed a common-sense process—a survey—was underway to establish a boundary. That was before an agent in tactical gear showed up at their door and charged them with theft of government property.
