Down at Satank the Crystal River gives itself up to the Roaring Fork, and on a July dusk the water goes the color of cold glass while the swallows work the surface. Grow Green Now LLC keeps the yards on those river-bottom lanes looking like somebody loves them: grass cut on a set schedule, borders trimmed so the beds have a clear line, the whole place tidied and hauled out at the ends of the season. It is unglamorous work and it shows immediately, which is the pleasure of it. Carbondale summers run hot and dry between afternoon storms, so timing the cut matters as much as the cut itself. Turn onto the street and you can tell which lawns were on the route.
