Oak Lawn's blocks are laid out generously — ranch houses set back behind front lawns, parkway trees arching over the side streets, Stony Creek slipping along the edge of the neighborhood. Camargo Landscaping runs the mowing route through those streets on a weekly clock, which is what a lawn here demands from the first warm rain in May until the ground stops giving. Trimming tight along the chain link, edging the sidewalk seam, sweeping the clippings back off the drive so the finished yard is the only thing you notice. Spring means the cleanup that hauls off everything winter parked in the shrubs; fall means leaves, week after week, until the parkway maples are finally bare. It is neighborhood work, and the whole block can see how a yard was left.
