BERKELEY HILLS (KCBS) — Berkeley Lab’s annual goat herding through the hills above Centennial Drive delayed traffic briefly Friday afternoon, but drivers were treated to an impressive show as hundreds of goats raced across traffic lanes to continue chomping their way through the tinder-dry Berkeley Hills.

The Berkeley Lab communication department posted the video to Facebook, saying, “Goats gone wild! We utilize goats at the lab in order to keep our grasses short and reduce fire hazards.
