From the bluff at Stark Park the Merrimack runs wide and slow, and the North End lawns above it change character four times a year. Carl Smith Lawn Service and Snow Removal follows that turn — mowing, trimming, and edging through the growing months, cleanups when the maples finally give in, then blades and shovels once river fog starts freezing on the sidewalks. Winter here isn't one storm but a long argument, and opening a driveway at four in the morning so somebody can leave for work at six is the whole job in a sentence. In July that same driveway gets a crisp border and a lawn cut at the height that keeps its roots cool. Same properties, same care, two entirely different sets of tools.
