On the towpath at Gebhard Woods, the old I&M Canal keeps one straight green line through Morris, and a lawn can hold a line just as true. All Year Round Landscape Services, Inc. mows, trims and tends yards across town, then turns that same attention to snow when the calendar asks for it. Summer here is thick with river-bottom shade and the smell of cut grass drifting over back fences; winter is another job altogether — plow and shovel, drives opened before the coffee cools. Both halves get the same care: a lawn left even from curb to fence, a walk taken down to the pavement. The pleasure is in the finished look, a property that seems to have been waiting for you all along.
