July evenings in Bayville hold their light late, the bay flat and pink past the end of the street, a mower still running until the last of it goes. R & K Lawn Care takes the cool end of those days for cutting and trimming, when the grass is dry and the heat has finally broken. Edging tightens the walks and the driveway; the blower clears whatever the pass leaves on pavement. Sandy yards along this stretch burn fast in high summer, so the grass is left tall enough to shade its own ground. A lawn that stays green into August around here is a lawn somebody thought about.
