Driving West

I was in a car driving cross country to the west.  I had a female companion who was going to meet somebody to get married.  We drove through countryside with lots of wheat growing.  We came to a city and there was a factory on the side of the road.  The employees had to cross the road to get from the parking lot to the factory.  There was a warning sign and I slowed down.  Right in front of me a bunch of employees crossed the road and I had to slam the brakes hard to stop from hitting them.
