The hills around Pontiac are moraine — gravel and sand shoved into ridges by ice and simply left there, which is why nothing in this county stays flat for long. Michigan Lawn and Landscape mows that rolling ground, out along Opdyke and the roads that ride its swells, where May turns everything green nearly overnight. The routine is cutting at a set height, trimming whatever the slope hides, and edging walks and drives back to their true shape. Seasonal cleanups sit at either end of the calendar. The best view of the finished work is from the bottom of the drive, looking up.
