Early summer evenings in Suffield run long. Down along the river the light stays on the water at Sunrise Park well after the fields have gone into shadow, and Stony Brook keeps its own cool under the trees. K & B Landscape & Lawn Maintenance Services tends the town's yards through those weeks — weekly mowing, trimming and edging, bed maintenance and mulch, cleanups in spring and again when the leaves come down. There is a particular pleasure in leaving a property at dusk with the lines still fresh in the grass and the walks blown clean. Suffield notices that kind of thing.
