“We go, son. Now,” Dad said absently. He took a long step up and pulled the driver’s door shut with a grunt, the mosquito net clinking against the thick safety glass of the windows. He stashed the gas mask between the seats. Dad’s worn leather cowboy hat was pulled up and a sweat covered his forehead, his gray, bushy eyebrows riddled with tiny drops. He propped his massive body into the driver’s seat, wrinkling the plastic coat that covered most of what was inside, and rammed the car key into the ignition.
