Morning arrives at Etra Lake before anyone is ready for it, mist standing on the water and dew heavy enough to bend the grass. That early hour is when BeLawnSmart likes to start mowing East Windsor yards, while the blades are sharp and a lawn still holds the shape of the night. Cutting here means reading a coastal-plain yard — flat, wide open to the sky, quick to leap after a warm rain. By the time the sun clears the trees along Rocky Brook, the mow lines are drying in soft parallel rows and every bed edge runs clean as a drawn line. It is a small thing and a whole thing at once: a yard off Etra Road that reads as cared for from the street.
