The name is a joke that turns out to be true, because a lawn wants what a good haircut wants: an even line, clean sides, nothing scalped. Andres Lawn Salon takes that seriously on the tight brick-lined blocks near downtown Aurora, where lots are compact and every mistake shows from the sidewalk. Weekly mowing, edging along walks and drive aprons, trimming around stoops and porch posts, and the cleanups that open the year and shut it down. At noon in July the grass smells like the whole idea of summer and the passes come out straight. Small lots, done exactly, add up to a street that looks cared for.
