On a Saturday in June the carousel at Slater Memorial Park is going around and half of Pawtucket seems to be under the trees. The lawns nearby have their own weekly rhythm, and Brianna's Lawn Care keeps it — mowing, trimming, edging and hauling off the clippings so a yard is finished rather than merely cut. Small city lots hide nothing: you can see every wobble in a line, so the lines have to be true. A crisp edge along a walk does something to a whole house — it says care from the sidewalk before anyone reaches the door. Week by week through the growing season, that's what gets done around this city.
