By late October the oaks around Levagood Park let go all at once, and half of Dearborn wakes up buried. Clean Ups LLC does what the name says in both directions — raking and hauling the autumn load, mowing and trimming through the growing season, then plowing, shoveling, and salting once the leaves have been replaced by something colder. There is something restful about an empty yard in November, edges swept, nothing left in the beds. Then the first real snow arrives and the same driveways get opened the same way. Two seasons, one habit: leave the place better than you found it.
