Our family lived in a city without elms called The Elm City, on a street with no willows named Willow Street. Uncelebrated trees shaded our part of the road, sturdy oaks and mature maples, their branches so thick with leaves that they created a blind curve just before the intersection where the street straightened past our house and made its hard line for the highway. Cars traveled at a clip down Willow Street, especially at night, and because of the curve it was impossible to see them until they’d nearly reached the street lamp glowing lambent out beyond my bedroom window. Yet lying awake under the covers I could hear those cars coming, and never more distinctly than on rainy fall evenings when the wind had blown a scatter of acorns across the pavement. I’d be tensed against my pillow, listening to the whoosh of tires closing fast over wet asphalt and then, an instant later, a brief, vivid flurry of noise, the rapid, popping eruptions of a dozen flattened acorns, before the whoosh receded into traceless silence as someone else hurried out of town. Long before I saw that I came from a place people wanted to leave, I knew eager they were to get away.
