In Dillon, Mont., 180 miles northwest of Yellowstone, a rancher in late August found the carcasses of 122 purebred adult sheep strewn in bloody heaps in his pasture. It was the worst livestock predation in memory -- an example of the ability of wolves to kill for the pure pleasure of it -- and wildlife officials authorized the killing of the entire pack.

I like sheep and elk as much as I like wolves. Now what do I do?
