Dusk over the Chattahoochee comes in humid and gold, and the whitewater below Uptown keeps making noise long after the paddlers go home. RiverCity Lawn & Landscape takes its name from that water and its work from the blocks above it, mowing, edging, trimming and clearing clippings for Columbus yards on both sides of the ridge. Grass grows thick in this river air and asks for a firm, regular hand. A cut lawn with a clean border holds its shape right up to the next visit. That shape is what the crew is after, week after week.
