Argyle Lake sits flat as pressed tin in the early hours, and the village wakes slowly around it. All Pro Lawn Service works the streets that fan out from that water, mowing, edging and feeding lawns on Long Island's South Shore. Babylon grass grows fast in the damp spring air off the bay, and the answer is simply to show up and keep it honest. There is real satisfaction in a clean line where turf meets walkway, and in a yard that reads as cared-for from the curb. By the time the afternoon comes on, the work is behind them and the lawn is the only thing speaking.
