Summer evenings in Highland Park sound like screen doors and window units, and the back yards behind these houses are small, fenced, and used every single day. Ruizlandscaping keeps them that way — cutting and trimming right up to the fence line, edging the walk, laying mulch in the narrow beds along the foundation, hauling clippings out through a gate barely wide enough for the barrow. When the season turns, the work turns with it: plowing, shoveling walks and steps, and salting the shaded spots where ice hangs around for days. It is a borough of short blocks, and a crew that already knows which driveway drains where can get through a lot of them in a morning. The yards look looked-after, and that reads from the street.
