The Augusta Canal keeps its own weather — a green corridor of moving water and old brick that sits a few degrees cooler than the streets above it. Rollin's Landscape Co., Inc. works the blocks on either side of that water, where mill-era houses stand close to the road and a front yard is measured in feet rather than acres. Mowing, edging, shrub and hedge trimming, mulch laid dark and even against a clean bed line: small moves that add up to a property somebody is plainly looking after. Midsummer along the towpath is honest work, the heat standing still by noon and the trimmer line singing anyway. By the time the trucks pull off, the grass is level, the beds are squared, and the sidewalk is swept back to bare concrete.
