Where the Roaring Fork gives itself up to the Colorado, the morning comes in cool off the water and stays that way an hour longer than it does uphill. ACE'S LAWN & LANDSCAPE SERVICE LLC works those river-bottom yards in Glenwood Springs, mowing while the grass still holds its night weight and trimming back to the fence line before the sun clears the ridge. Watered ground down here grows fast and unevenly, so the work becomes a rhythm — cut, edge, blow the clippings off the walk, then look back down the length of it. A clean edge along a Glenwood sidewalk is a small, deliberate line drawn between the wild valley and the yard someone tends. That line is the whole point, and it is worth coming back for every week of the season.
