Early mornings at Lake Arlington the path fills with walkers before the sun clears the trees, and the whole northwest side of town smells like cut grass. A & B Sanchez Landscaping is part of the reason — mowing yards on a weekly turn through a Cook County summer that pushes turf hard. Trimming handles fence lines and the tight strip beside the garage; edging gives every sidewalk its shoulder back. Spring cleanup clears away the winter's litter, and fall cleanup takes on the parkway maples, which drop more than seems reasonable. A block of Arlington Heights lawns all cut on the same day is a genuinely fine sight.
