The North Branch of the Chicago River bends through Albany Park in a slow green curve, and when a storm rides in on a northeast wind the neighborhood goes white from the water outward. JC Prime Tree and Snow Removal Service works those blocks in the thick of it — plowing driveways, cutting a clear walk to the door, spreading salt on stairs and aprons so the second freeze has nothing to grab. The bungalow and two-flat streets near Lawrence and Kedzie sit close together, which means shovel work as much as blade work, and both get done. A Chicago winter is less about one great blizzard than about the steady accumulation of nights like this one. An open entry at six in the morning is the whole point.
