A cold mid-October dawn will soon reveal the first frost of the season. The growers have advanced weather-detecting equipment and are already in the fields preparing to protect the more fragile vegetables from the damaging conditions. The Zellers commonly run water lines throughout the night to create a watery mist that helps to keep frost from forming on the crop. They make every effort to save their final crop of the season. It is also a symbolic time for migrants working in the northern states because they know they will soon be done for the season and will need to migrate south to find work.
