By September the air in Los Lunas carries roasting chile, and the Rail Runner's horn drifts across the valley a couple of times an hour. Ramos Landscaping and Maintenance moves through that season with mowing on a set rotation, string trimming around posts, walls and tree bases, and edging that keeps a lawn from spilling onto the concrete. When the cottonwoods along the Rio Grande finally turn and drop, cleanups take the leaves and fallen limbs back off the grass. Each yard is left blown clear with the clippings hauled away. A tidy lawn in that low autumn light looks like the valley is being looked after, and it is.
