Along South Platte Park the river runs low and bright and the prairie grass leans all one way whenever the wind decides to come down the valley. Open Space Solutions LLC keeps lawns and grounds in that same wind — mowing, edging, string trimming, and the seasonal clearing that keeps a property from going shaggy at the margins. The name fits the country: wide ground, big sky, and turf that has to be cut with an eye on how fast this climate dries it out. What gets left behind at the end of a visit is an even sweep of green, borders drawn clean around walks and beds, and clippings hauled off instead of scattered. On a clear Littleton afternoon, with the mountains stacked up blue on the horizon, a tidy lawn is a small piece of order set against a lot of open space.
