Down by Port Newark the sky is enormous and the cranes stand over the bay like a row of herons, and the wind carries salt into every yard between the water and Dayton Street. P&B Yard Smart, LLC cuts and keeps the grass that grows in that hard, bright corner of the city — mowing, trimming, edging, and the clearing work that takes away the grit. July here is hot asphalt and gulls, and a lawn cut level in the middle of all that is a small act of defiance. Straight lines, clean fence rows, nothing left on the sidewalk once the truck moves on. Even a strip of green reads as green when somebody is looking after it.
