The rail line still runs through the middle of Richmond, and a freight rolling by is the town's oldest way of marking the hour. Avay Landscaping LLC keeps a similar sort of reliability — mowing, trimming and cleanups while the ground is green, plowing, shoveling and salting once it is not. Summer afternoons smell like cut grass and warm ballast; winter mornings are headlights, breath in the air, and a blade finding pavement. What does not change is the finish: a lawn squared off at the edges, a driveway cleared corner to corner. Two seasons of work for Richmond and its neighbors.
