The Ho-Ho-Kus Brook runs the length of the borough, and the yards nearest it stay green a week longer than the rest in a dry June. Cypress Lawn Maintenance works that ground on a weekly rhythm — mowing, string trimming along fence lines and the brook bank, edging the walks, and clearing beds when the season turns. Lawns in a village this size are seen up close, from the sidewalk, by people walking to the station, so the small things carry: a straight edge, a clean line at the driveway, no clippings left on the stone. On a Thursday afternoon in early summer the whole street smells like cut grass and wet brook stone. That is a day's work you can stand at the curb and look at.
