At noon in July the pavement near the McKeesport Marina throws the heat back at you and the river is the only cool thing in sight. GT Landscaping runs the mowers early and finishes the trimming while there is still shade on one side of the street. Weekly cuts, tight work around posts and hydrants, an edge along the walk, then everything blown clean, because grass holds up through a hot stretch when somebody keeps it on a rhythm. Pulling up to a yard that is already sharp from last Thursday is its own quiet reward. McKeesport and its neighbors along the water are the regular route.
