Seemed to be at least one street that was transparent, down there, lit from below, like it was paved with glass. Hardly any traffic. Maybe they hadn’t designed that yet. She thought she’d seen something walking, two-legged, at the edge of woods, or a park, too big to be human. Some of the vehicles hadn’t had any lights. And something huge had sailed slowly past, out beyond the receding towers, like a whale, or a whale-sized shark. Lights on it, like a plane.
