The blizzard that pounded the Northeast on Friday was no Hurricane Sandy, but it has left thousands of people without power throughout the region. For some households, losing power may be no big deal. But if you're old or disabled, this can be a dangerous situation.
The problem is that it's hard in most communities to know which residents may badly need help. After Sandy, hastily organized volunteers knocked on doors in buildings in Rockaway and other places to identify the old and frail.
