Ashley Boulevard catches the wind straight down its length, and in a January storm the sidewalks drift over nearly as fast as you clear them. ESTANIS LANDSCAPING & MASONRY works that against-the-clock stretch: plowing driveways and lots, shoveling walks, laying salt and sand where the ice sets up hard overnight. The snow that comes off the bay lands heavy and wet, then stiffens by dawn, so arriving early matters as much as anything else. Piles go where they will not block a sightline or dam the melt when it finally runs. The measure of a night's work is a clean apron and a driver who never once spun a tire.
