In November the bosque along the Rio Grande turns a gold so complete it changes the color of the light on the whole block. Greenland Llc works those cottonwood-shaded streets, mowing, trimming, edging and hauling away the enormous leaf fall that comes with living near the river. Bosque yards run cooler and damper than the mesa, and grass there rewards a cut left a little on the high side. By the time the branches are bare the lawns are clean, the borders are clear, and everything is set up for a quiet winter. Come the first warm week, the mower is back out on the same streets.
