By the middle of June, Madison Park is deep in shade and the grass everywhere in Quincy is growing faster than anyone can quite keep up with. Best Kept Lawn, Inc. spends those weeks mowing, trimming and edging yards across town, chasing that growth one visit at a time. River-valley humidity makes for thick turf and a heavy first pass, and the smell of it rides in the truck the rest of the day. What lasts is the look of a finished yard at dusk: even height, clean borders, nothing shaggy at the fence line. The route runs through Quincy and out to the towns nearby.
