"SPRINGERVILLE, Ariz. -- On a luminous fall afternoon, a couple of Carey Dobson's sheep graze in a pasture stretching across a high valley edged with ponderosa pines. A wire fence keeps them from wandering into the adjacent road.

But this is no ordinary fence. All along its length, long slips of magenta plastic flagging wave in the wind, like streamers on a parade float. No one knows exactly why, but wolves typically stay clear of these decorated fences."
