September lets up. The heat finally breaks, the nights cool down, and Commerce City lawns get a second wind of green better than anything June ever managed. The 303 Green Genie takes the neighborhoods block by block through that stretch — Rose Hill, Adams City, the older streets off Kearney — mowing, edging, trimming and clearing everything off the walks before moving on. Small yards, close together, each one wanting the same short list done right and done on time. It's an unfussy kind of work with an immediate payoff: pull up to a rough yard, leave behind a tidy one, and go do the next.
