Pig farms are disgusting. I used to drive by one on my way to work in
the days before AC and power windows wera almost universal, and it was a
full size pick up, so a long way to reach across to roll up the window.
I occasionally forgot to roll up the windows before I got to the pig
farm, and once that stench got in I needed about 10 miles of driving
with windows open to get it cleared out.
