Sandy-hit areas sputter back to life amid destruction, heartache

Buses hauling commuters down roads strewn with debris. And shivering people, peeking from bulky sweatshirts, waiting hours to fill their gas cans at stations. But challenges remain, including fuel and food shortages, and lack of electricity to more than 3.3 million customers in 15 states and D.C. Days after Superstorm Sandy barreled ashore Monday, survivors pleaded for basic necessities.
