Webb Memorial reaches out into Hingham Bay on a slim green arm, and from the far end the harbor islands lie scattered around like stepping stones somebody left behind. South Shore Landscaping Corp. works the mainland behind that view — lawn care from the first spring cut through the last leaf run, and snow removal once the bay wind turns bitter. A summer week is mowing, trimming and edging; a winter night is plowing, shoveling and spreading salt across drives and walks. Weather comes off the water fast here and leaves the same way, so schedules bend and the work still gets finished. What lasts is how the place looks once the trucks have gone.
