Sam stopped at the crossroads. There was a 4-way stop. He waited a full five seconds before moving across the intersection and down the country road, ten miles from the nearest town. His farm was one of the sections of land which met at the crossroads. The others were unoccupied. Their owners had just walked away from the long-defaulted mortgages leaving their 640 acres to the weeds which could grow. The ground was so poor that no agribusiness even cared to lease the land from the bank. He travelled the road twice a day, but never met a soul until just outside the town where he had a part-time job. "Simon-pure, that's you," said his wife with a wry smile. She, too had a part-time job, though only twice a week. She smiled as she spoke because Sam was also a rock, a hard worker, a loving husband.
