June mornings in Merrimac arrive with mist still lying along Cobbler's Brook, and the grass holds so much dew that the first pass of the day leaves a dark stripe you can read from the road. Birch Hill Mowing and Property Maintenance works those hours on purpose — mowing while the air is cool, trimming close along fence lines and foundations, then edging the walks so the lawn ends where it is supposed to end. Spring and fall cleanups clear what the wind leaves behind on these hill roads above the Merrimack, and the ordinary upkeep in between keeps a property looking cared for rather than merely cut. Merrimac is a small town where a yard is seen by everyone who drives past it, and that is reason enough to do the corners properly. By the time the sun clears the treeline, the stripes have dried and the place simply looks right.
