On a June evening south of Delta the hayfields run right down to the Mason-Dixon line, and fireflies come up out of the grass like the ground is letting go of the day. MB LawnCare keeps the yards along those roads on schedule — regular mowing, trimming around fences and posts, edging, blowing walks and drives clear, hauling off clippings and bed debris. Properties out here are wide and the mower makes long passes; there is a rhythm to that which is hard to describe and easy to see in the stripes. A lawn that has been kept, week after week, looks different from one that has been rescued. That difference is what the work is for.
