More than half a century ago, Idaho Fish and Game decided they wanted to hunt mountain goats so they captured some near Coeur d'Alene and released them into the Snake River Range. Fifty years later, these goats are threatening the extinction of the Teton Bighorn Sheep.

In this episode, we try to understand how it came to this.
