About 350 wouldn't cooperate with the annual Great Montana Sheep Drive.
The flock even got lost behind a bar in the town of Reed Point.
The Billings Gazette reports a white sheep with black legs and a black head looked like it might lead the herd down Main Street.
But the entire flock turned around and ran back out of town.
The sheep may have been confused by rain.
The sheep drive raises money for community projects.
