The sunken garden at Phillips Park was a limestone quarry once; now it is a green bowl that fills with April light while the rest of Aurora is still deciding whether spring has arrived. Loera LawncareLLC starts its year about then — first cuts, the clearing of whatever winter left behind, the mower's first honest workout. Through summer it is steady mowing, string trimming around fences and posts, and edging that gives a lawn its outline. Grass moves fast in this valley soil once the warm rain sets in, and staying ahead of it is the whole job. Aurora yards, week after week, looking like someone tends them — because someone does.
