Out toward Gillespie Field the lots run flat and open and a small plane crosses low overhead every few minutes all summer long. Owens Lawn Care and Landscaping LLC mows that side of El Cajon — big, simple lawns that reward a straight line and punish a lazy one. Trimming around posts and mailboxes, edging the length of the drive, hauling off what comes up behind the mower. The valley light out there is flat and hard at noon and gold by five, and fresh-cut grass takes both well. There is a plain satisfaction in a yard that is finished and stays finished a while.
