HARTFORD, Conn. (AP) — Crews are working feverishly to restore power to nearly 1.2 million homes and businesses plunged into darkness by a freak weekend snowstorm in the Northeast.Connecticut had the most customers left without power Wednesday — more than half a million. The president of the state's largest utility says "we understand the frustration everybody is feeling."He says that more than 100 new power crews are joining current workers and that thousands more customers should have lights and heat again by Thursday morning.Some schools were canceled for a third day across the region, and many people were still staying in shelters.The storm dumped snow from Maryland to Maine and was so wet and heavy that many trees buckled and took out power lines.
