Madaket keeps the last of the light every evening, the sun dropping into the water past Eel Point while the rest of the island goes dusky. New Look Landscaping Company mows, edges and tends the yards out at the west end, where the salt wind pushes everything sideways and lawns have to be coaxed along. Sand runs right up to the grass here, and holding green against that line takes patience and a steady week-to-week hand. A late cut on a summer evening, the mower finally quiet, gulls heading off toward Tuckernuck — that is the good part of the job. The result is a yard that looks effortless, which is the whole point of it.
