by Paula Dunning Rachel is driving the riding mower back and forth across the lawn, the first mowing of the season. It’s springtime-cool—she’s wearing a light jacket, and a bright red scarf holds back her greying curls—but the midday sun is warm on her back. As she backs up to manoeuver around the hawthorn bush, she glances across the expanse of green to the house, where the rose bushes beside the deck are just putting out leaves. When she and Tom moved onto this farm forty years ago, a small yard surrounded the house. Back then, she pushed an old mower that spewed out black smoke while the kids piled up the clippings to make hay for toy cows.
