Greeley was laid out as a colony town on a grid of wide, straight streets, and that geometry still rewards a straight mow line. Centennial Outdoor Creations LLC. works with it: mowing, edging, trimming and seasonal cleanups that follow the square corners of the old blocks and the newer subdivisions west of town. When the cottonwoods stand bare and the grass goes dormant, the work becomes snow — driveways, sidewalks and entries cleared, ice treated where the shade holds it longest. A yard whose lines answer the street's lines simply looks right. Greeley, Evans, Windsor and Johnstown.
