My daughter-in-law Liz was driving her son and daughter to school one morning. It was spring and the farmers were out in full force getting fields ready. Soon an awful smell filled the car. Liz explained that farmers spread manure on fields to make crops grow better. Isaac, who is four, asked what manure was. Liz told him it was poop. "Oh Gross," he said. "The farmers are putting cat poop on the fields."   Submitted By: Jean Way
