WAYLAND, Mass. (AP) — Hundreds of thousands of people across the Northeast shivered at the prospect of days without heat or lights after a freak October snowstorm over the weekend, and many towns postponed trick-or-treating Monday in what seemed like a mean Halloween prank to some children. Families huddled under blankets and winter coats at home or waited out the crisis in shelters as utility crews struggled to fix power lines brought down by the storm. Hundreds of schools closed, giving youngsters one of the earliest snow days on record.
