Everything in Pawtucket eventually leans toward the Blackstone, which drops over the falls downtown and keeps going whether it's July or January. AK LANDSCAPING keeps pace with it on both sides of the year — mowing, trimming and lawn upkeep through the green months, then plowing and clearing driveways, walks and lots once the river runs cold. Mill-city yards are small and particular, hemmed by fences and stone, and they reward somebody who bothers with the corners. In winter that same attention shows up as a driveway scraped down to the pavement and a path to the door wide enough to carry groceries through. Two seasons, one habit: leave the place better than the weather left it.
