A well-tended yard hands something back to the people who live on it — grass that eases you off a long day, a front walk clear enough to carry the groceries in without a second thought. That is the work Miranda's snow lawn care keeps up across Lynn, where streets of old brick mill buildings slope down toward Massachusetts Bay and the wooded ridges above the city hold their green over the rooftops. Through the warm months the mowing keeps a lawn even and its borders trim, so even a small North Shore lot reads as looked-after from the sidewalk. When the coast turns hard and the salt wind comes off the water, the plow and shovel open the driveways and walks again, often before the light does. It is plain, steady work, and it leaves a place looking cared for.
