March brings Berthoud its heaviest snow, wet as fresh cement, hanging on the maples along Mountain Avenue until the branches bow. Before the storefronts unlock, AGT Landscape & Design is out with the plow lights on, clearing lots and driveways and breaking the shovel line along the sidewalks so nobody steps into slush at the curb. Heavy snow rewards patience — a slower blade, a cleaner scrape, edges cut square instead of smeared. There is a plain pleasure in standing back at sunup and seeing a lot swept end to end while the eaves are still dripping. Come afternoon, the Colorado sun does its half of the job on whatever is left.
