Late in the day the Book Cliffs north of Fruita go the color of a struck match, and the light comes down the valley long and low across every lawn in town. Aaron's Lawn Care Inc. works that hour often, mowing and trimming and edging while the air finally lets go of the afternoon. A lawn cut at that time of day shows every line it has, and the crew likes it that way. Between cuts come the cleanups — beds tidied, drifted leaves gathered, the margin against the walk brought back to a clean straight run. Fruita asks a great deal of a green yard, and keeping one takes turning up, week after week.
