Southwest of Manchester the land breaks into the Irish Hills, glacial ridges with lakes tucked between them and lawns that run all the way down to open water. Irish Hills Lake Services works those shorelines and the fields behind them — mowing the slope toward the dock, trimming the edges by the dock posts and the steps to the waterline, gathering clippings so nothing drifts out onto the lake. Cottage lots need a cutting interval that can keep up through the deep green weeks of summer. Spring openings and autumn cleanups carry a yard from first thaw to last leaf. A lawn that ends at open water deserves an edge worth looking at.
