Some days on a dirt road only one car might pass. Some roads probably only feel the grip of a tire on its back once a week. Or less, who knows. Summer and winter are the slowest times, when the countryside feels most empty, and the skies the biggest. However, in spring and in fall, when farmers rush to plant and harvest grain and canola the roads come alive with machinery and the air is abuzz with the hum of heavy equipment and heavy with suspended particles of dust. At night the tractors look like space ships, for what other form of equipment has so many lights, shining so bright?
