When a blizzard settles over Worcester, the wind wraps around Bancroft Tower and comes down the Salisbury Street hills carrying everything it picked up on the way. NEW ENGLAND SNOW REMOVAL runs into that: plowing driveways and parking areas, shoveling front walks and side entries, pushing the banks back so the next storm has somewhere to go. Ice management follows the blade — salt and sand across the slopes, the aprons and the shaded stretches that never catch midday sun. A city built on seven hills makes clearing a question of angles, and every driveway has its own right approach. The measure of a night's work is a car that rolls out at six in the morning with no shovel in the trunk.
