On Detroit's side streets the morning arrives flat and wide, the sun sliding down the block until it finds the river. That is when 620 Express Lawn care gets moving — mower off the trailer, string trimmer humming along a fence line, dew still darkening the toes of their boots. The work is mowing, edging and the steady upkeep that keeps a front yard looking like somebody is home. A city lot can go from shaggy to sharp in a single afternoon, and the whole difference is one clean line where grass meets sidewalk. By the time the block is finished the clippings are swept off the walk and the yard reads crisp from the curb.
