Morning in Rocky Hill comes up off the Connecticut River as a low silver fog, and it burns back slowly to leave the lawns still beaded from the valley's damp — which is just when the mowers roll out. Tom's Landscape Company works the flat, generous ground between the river's edge and the traprock ledges to the west, drawing clean lines across yards the floodplain keeps stubbornly green. There is a plain pleasure in a strip freshly cut, the grass laid over in even rows, the border trimmed sharp against the walk. Come autumn, when the silver maples along the water let go of their leaves all at once, the raking and clearing carry on until the turf can breathe again ahead of the first frost. It is honest work, and it leaves a Rocky Hill yard looking cared-for all the way from the road.
