A painter learns to see a line before anything else: where it should fall, how straight it holds, whether the eye catches on it. B&B Painting and tree trimming brings that same eye to a winter morning in Alamosa, when the low sun comes down State Avenue and every plowed edge throws a blue shadow. The work is snow here, driveways and lots opened up, walkways cleared, ice knocked back at the steps and entries where it does the most harm. Valley snow squeaks under a boot and drifts wherever a fence or a building gives it a reason, so the crew reads the wind as much as the forecast. What a customer sees at eight o'clock is a clean edge and open ground, which is the whole point.
