Stone Church Brook comes out of the cleft in the rock above Dover and runs cold all summer, which tells you something about the ground here. Supreme Lawn Care mows the yards downstream of it, holding the cut even where the valley floor rolls and the shade shifts across an afternoon. Trimming and cleanup finish every visit; a lawn ought to look tended, not merely shortened. When winter closes the valley in, the work becomes plowing and shoveling — drives and walks opened while the light is still gray. Lawn care and snow removal for one town, worked closely.
