March mornings in San Carlos come with wind off the open ground and mesquite just beginning to leaf out. Native Dynamics General Contractors mows, trims and hauls away what winter left behind, so a yard meets spring without a season's worth of debris packed into its corners. The work lives on the edges out here — the clean line where gravel meets grass, a shrub cut back before the heat arrives, the strip along the road squared off. Past the last houses the land runs unbroken to the far ridges, which makes a tended yard read like a deliberate act of order. San Carlos, Peridot and Bylas are all within an easy morning's drive.
