Come September the chamisa goes off like a yellow flare along every roadside in La Cienega, and the magpies get loud about it. It is a good month for grass here — nights cool, light softening, lawns finally comfortable — and J&R LANDSCAPING SERVICE LLC uses it well, mowing on a steady turn, cutting growth back from posts and walls, hauling off whatever the season drops. Their work is the ordinary kind that keeps a property from slipping: even height, defined borders, no forgotten corner behind the shed. Neighbors notice, though usually only in the way you notice that something looks right. That suits them fine.
