BRG Landscaping LLC keeps its hands in the salt-tinged ground of Bridgeport, the Park City where the Pequonnock River loosens into Long Island Sound. Through the growing months its lawn care moves yard to yard across the old brick blocks, mowing lines pulled straight and edges pared clean where grass meets the sidewalk and the harbor light comes in low. When the cold settles over Fairfield County, the same work turns to snow removal — driveways and walks cleared ahead of the morning traffic while the Sound lies grey and patient. There is a quiet satisfaction in a drive scraped down to bare pavement and a lawn that holds its shape from the first thaw to the last leaf.
