"2,500 Sheep Cause Traffic Jam on Idaho Highway"

A herd of 2,500 sheep crossed a highway in Idaho, guided by ranchers and sheepdogs, on their way to higher elevation for the summer. The sight attracted a crowd of about 300 people, the largest turnout in 15 years, according to a spokesperson for the Idaho Rangeland Resources Commission. The tradition of moving sheep to graze in the forest dates back around 100 years and helps prevent fires and invigorate plant growth.
