CAUTION: cattle drive ahead

REALLY! I was driving to the Idaho Falls airport and saw the sign "Caution: Cattle Drive Ahead". Before I knew it, I was surrounded by hundreds of cattle running through the ditches and crossing the road whenever they wanted. The best part was the cowboys on four-wheelers moving the cattle along. Once I worked my way to the front of the pack I saw one lone sheep running along side the cows. What a random experience!!
