You can watch a summer storm cross Oakland County a good ten minutes before it gets here, the ground being flat, the skyline low, the light going green over the rooftops. The day after is the best day to work: soft ground for planting, beds that cut cleanly, grass that mows without dust. Lawn care in Hazel Park means the weekly pass, trimming and edging, mulch refreshed in the beds, shrubs kept in bounds and cleanups at both ends of the year. The city packs a great many houses into a small grid, so the difference one tended yard makes ripples out to the neighbors on either side. Green has a way of spreading down a street.
