Fifteen miles west of downtown Detroit, on flat suburban ground where the yards are small and the blocks run long, one truck can cover a lot of Garden City in a day. That ONE Guy's Lawn Care LLC is exactly that — mowing, trimming, edging and hauling clippings, house after house, with spring and fall cleanups when the season turns over. The same person shows up each week, learns which gate sticks, remembers where the sprinkler head hides in the back corner. A one-person route means the details never get handed off to anybody else. By evening the block has a rhythm to it that wasn't there at noon.
