By two o'clock on a July afternoon the thunderheads are stacking up over the Front Range, and the work gets done in the bright hours ahead of them. ClearSky Property Services handles the mowing, trimming and lawn upkeep that keeps Lone Tree properties looking deliberate from the curb. Out here the sky does most of the talking — a hundred miles of it, from the Palmer Divide north to the city glow — and a lawn cut tight and even is the one square of order underneath all that weather. Beds get trimmed back, edges get run, drives and paths get cleared of what the mower throws. It is steady, repeating work, and the payoff is a property that looks the same kind of good week after week.
