150 years and NOW they want it.

Armed federal agents have descended upon a Nevada cattle ranch, and will soon settle a feud with 67-year-old rancher Cliven Bundy, who has contested the U.S. government’s right to tax and regulate property that has been in his family since 1870.

Bundy’s disagreement with federal authorities began more than 20 years ago, when he first refused to pay mandatory fees to the U.S. government. His family has owned the ranch in Clark County, Nevada, for more than 150 years, and the federal government has no right to make him pay to herd cattle on his own property, he claimed.

Bundy is willing to pay fees imposed by county officials, but says he doesn’t owe the U.S. Bureau of Land Management anything.
