Inside the cab, the air was hot, and we peeled of layers of jackets and sweaters, sitting in loose t-shirts and baking slowly. The sunroof whistled and moaned, covering up any music we played if it lacked intensity. So we played big rock music, country with twang, anything that could battle with the trumpetting wind that endlessly shoved against us like a drunk pushing past us on a bus, the wind heading down from the Rocky Mountains, over my shoulders and out across the flattest parts of the Earth.
