Late August in Boulder Junction carries a particular light — low and gold, coming sideways through the birch by six in the evening — and it shows every line in a yard. Elite Landscape Curbing LLC works in lines: continuous concrete edging poured to follow the curve a bed actually wants, borders that hold mulch on one side and grass on the other and keep the two from arguing. Around these lakes the ground is shaped by glacial stone and old pine roots, so no two runs of curbing ever take the same path twice. Alongside that come the ordinary good things — mowing, trimming, keeping beds neat while the growing season lasts. The reward is simple and it keeps: come the next thaw, once the sand and needles are raked away, the shape is right where it was set.
