Where the Au Sable finally lets go into Lake Huron, the ground near Old Orchard Park lies flat and bright and green right down to the water. Wier's Lawn Care works those Oscoda Charter Township yards with mowing, edging, string trimming and the cleanups that open and close a northern Michigan season. August is the long stretch — heat, fast growth and the smell of cut grass carrying on the river wind. A sharp edge along a sidewalk and an even cut across the front is a small thing that changes how a whole street reads. Getting it right, week after week through the season, is exactly the point.
