South Tucson is one square mile with a mountain range on every side, and the first sun comes over the Rincons well before the traffic does. Arizona Rising Sun Landscaping starts in that hour — mowing, edging and clearing yards while the pavement is still cool and the doves are the loudest thing on the block. Small lots reward precision: a trimmed strip along the fence, a clean corner where the walk meets the drive, nothing left behind in the gutter. By the time the day turns serious the work is finished and the street reads tended end to end. South Tucson and the Tucson blocks that ring it are all within the day.
