I grew up in the Permian Basin between Lubbock and Midland. When I was ten-years-old I went to work for the farmer who raised cotton and grain next to our house. I have many fond memories, and some not-so-fond memories, of the six years I worked summers and weekends on that farm. One of the memories I have is of the County Agent coming out, stepping off ten feet of a cotton row and counting boll worms in order to calculate whether or not it would pay to spray for the boll worms.
