By dusk the traffic on Union Road has thinned to a trickle and West Seneca eases into its porch-light hour, when you can hear a mower two streets over finishing the last pass of the day. That last pass matters — it's the one the neighbors see, the one that leaves a lawn looking rested rather than merely shortened. In the other half of the year the light goes early and the sky over the Southtowns turns the color of wet slate, and the same trucks come back with blades down. Driveways get opened, walks get cleared, and a household gets its morning back before it has even begun. Lawn care and snow removal, kept steady in a town that swings hard between the two.
