By four o'clock in July the thunderheads have stacked over the Front Range and started drifting east, and everyone on the plains runs the same arithmetic: how much can get finished before that reaches us. Motors Lawn Care does that math for a living — mowing, trimming, edging and cleanups fit into the good hours and then completed properly rather than abandoned. Storm light on a freshly cut lawn is one of the better sights this county offers, dark sky over bright green. Afterward the air smells like rain and clippings, and the yard just sits there looking exactly right. That is the whole reason to take the extra pass.
