The big news tonight here in Boston is a fire in the Back Bay that led to power going out in huge swaths of Boston. Apparently the fire started in a utility building containing two large transformers. In order to fight the fire, it was necessary to cut power to the transformers. That has now led to a power blackout in Back Bay, Prudential Center, Copley Square, Chinatown, the Theater District, and Kenmore Square. They are saying now on TV that they are allowing people to return to their homes but they have no idea when power will be restored to this area.
