Saturday morning on the bungalow streets near 12 Mile is a chorus of small engines, and JD's Yard Men LLC is part of it early. The route runs the way the city is built — straight blocks, alleys, drives that end at a one-car garage — mowing, trimming, edging, then a clean sweep of the walk before moving on. In autumn the work turns to leaves, gathered and hauled off the lot before the rain packs them flat. It is plain work done on time, which in a neighborhood this close together is exactly what people want. A cut lawn on a summer Saturday is its own small piece of good news.
