Morning on the Pecos near Loving stays cool for about an hour, mist sitting on the water and the alfalfa fields still holding the night. Halo Services Inc. starts mowing early because of it, working through yards while the grass stands upright and the heat is still only a rumor. Trimming follows along fence lines, sheds and the base of the salt cedar, with the edges cut so a lawn holds its outline against caliche and concrete. Clippings and blown-in debris are cleared off at the end of every stop. In this corner of Eddy County a green, even yard is hard won, and it gets kept that way.
