At the blue hour out on Crow Point, the lights of the Boston boat slide across Broad Cove and the whole shoreline seems to hold still for a minute. Silver Fern Landscaping keeps the ground under those houses in order — mowing, trimming, mulch and cleanups through the green months, then plowing, shoveling and salt once the water turns steel-colored. Coastal storms here come in wet and sideways, and a sloped driveway needs clearing more than once before it is honestly clear. Going back the second time is the whole difference, so they go back. When spring returns, the same properties get mowed and mulched as though nothing had happened at all.
