Morning comes up the La Plata valley before it ever reaches anyone's yard. First the rim of the mesa, then the alfalfa, then the grass. Heckman Logistics LLC works that early stretch of the day, mowing lawns along the river road and cutting a straight border where turf meets drives and walkways. Trimmer work follows the mower into the ground a deck cannot reach, around posts, fence lines and the base of every cottonwood, and the cut grass rides out with the truck rather than blowing across a neighbor's gravel. By the time the heat stands up off the pavement, the lawns behind them are level, quiet and finished.
