Early on a summer morning the breeze at Mich-e-ke-wis Park comes straight in off the bay, cool enough to make seven o'clock the finest hour of the day to be cutting grass. Thunder Bay Lawn Ranger LLC takes that hour — mowing on a set rotation, trimming close to steps and swing sets, edging the sidewalk until the concrete reappears, tidying the yard in spring and again in fall. Patrol is the right word for it: the same streets, the same properties, checked and handled before most of town is out. Grass grows on its own schedule and the only answer is to keep pace with it. A tidy yard in the middle of a Lake Huron summer is a small, complete thing.
