July noon up in the north end of New Rochelle, around Wykagyl, and the heat sits still between the oaks while every lawn on the block leans toward brown. Serafin Lawn Sprinklers Inc works the mowing and the upkeep straight through those long weeks, cutting high when the sun is punishing, running a clean edge along the walks, trimming fence lines and bed borders so a yard keeps its shape even in August. The ground rolls enough up here that a lawn reads like a slope of light, and holding a straight line across a grade takes a steady hand. When the cooler weeks arrive, the same lawns get raked out and tidied so nothing mats down. It is the kind of work you notice mostly by how little you have to think about it.
