Because They Love Us and Want To Make Sure We Have Food

Or is it incentives? The virtues of self-interest:

FITCHBURG, Wis. -- While the wind chills that are expected in the coming days might keep many indoors, others have no choice but to be out in the elements.

Livestock farmers will be challenged this week by the frigid conditions not only to keep themselves and their workers safe, but also their animals, WISC-TV reported.

Farmer Pat O'Brien said that there are three kinds of workers people will find doing their job no matter the weather.

"You got snow plow drivers, you got postmen and farmers, of course," he said.

As an aside, I am pretty sure the weather should matter as to whether or not snow plow drivers are doing their job. I vote that they only do it when it is snowing.
