Spring mornings on the road between Roma and Rio Grande City start with chachalacas making a racket in the brush and the day already promising to be warm. RGV Home Detail LLC is out in that first hour, mowing while the ground is still cool and trimming around mailboxes, fences and the bases of the mesquite. Edges get cut in along drives and walks, and the clippings get blown clear so the finish looks deliberate rather than rushed. In this stretch of the Rio Grande Valley the difference between a mowed yard and an unmowed one shows from three blocks away. Every week the same, and every week the street looks better for it.
