Evening comes to this stretch of the Rio Grande like a switch thrown — the Robledos go rose, the adobe at Fort Selden holds the last of the heat, and the valley finally cools. Royalty Lawn Care and Landscaping likes a yard that looks right in that light: mown even, edged clean along the drive, trimmed tight where the lawn stops and the desert starts. Between Leasburg and Doña Ana the growing season runs long and demanding, and the work is the same each week, and it gets done. Cleanups take off whatever the wind and the cottonwoods leave behind. What remains is a small, well-kept green in a very large brown country.
