Jack pine and sand country: Beaver Creek Township sits in Crawford County where the Au Sable headwaters run cold and the soil drains almost as fast as the rain falls. Growing a good lawn here takes patience, and GroGreen gives it that — regular mowing, trimming, edging and cleanup on lots carved out of the pines south of Grayling. Mornings can be cool enough for a jacket into June, and the grass shows it, coming on slow and then all at once. Cutting around stumps, roots and pine shade is its own small craft, and the payoff is a clearing that looks intentional instead of accidental. By evening the smell of cut grass and warm pine hangs over the yard together, which is about as good as a northern Michigan summer gets.
