Saturday morning near Inkster Road sounds like one mower, then another, then the whole neighborhood at once. Michael Lawn Service moves through it a street at a time — cut, trim, edge, blow the walks clean, on to the next house. Nothing about lawn care in Dearborn Heights is complicated; it simply has to happen every single week, in the heat, whether or not anyone feels like it. Cleanups bracket the season at both ends, spring and fall. Come evening the block sits even and green, and the sprinklers tick on like nothing ever happened.
