It is called the Trailing of the Sheep.

Trailing of the Sheep is an annual October festival and parade in Sun Valley, Ketchum and Hailey, Idaho.

Blaine County is home to events and festivals throughout the year, including Wagon Days, Trailing of the Sheep Festival, Sun Valley Harvest Festival, and the Sun Valley for the Arts Wine Auction.

This week and next, field crews will sleep with a band of sheep as it makes its way down the "sheep superhighway" and then through Ketchum on Oct. 13 for the annual Trailing of the Sheep Festival, Stone said.
