Having grown up in Iowa, I know a thing or two about farmers. For example, they worry about rain...a lot. No rain, no crop. During one drought, I even remember my grandfather talking to his neighbors about how much it might cost them to get someone to seed the clouds.
Little did they know that it was actually just this easy:
Naked girls plow fields for rain
Some how, I don't think gramma would have been down with that.
