Early on a summer morning, before the heat stacks up over the plain, downtown Loveland is quiet enough to hear a flag line tapping outside the old Feed and Grain. Clean Air Lawn Care Northern Colorado keeps its mowing to that cooler end of the day where it can, cutting, trimming and edging yards from Loveland out across the northern part of the state. Grass at this altitude takes a great deal of sun and not much rain, so cut height and schedule are set to leave the lawn something to work with. There is a plain sort of pride in a finished yard — even color, tight edges, clippings swept off the walk. Spring and fall bring the cleanups, and the calendar comes around again.
