The twin beams of light that shine from the World Trade Center site to mark 9/11 have become a poignant symbol of the tragedy.

Now, the Municipal Arts Society is launching a fund-raising campaign to secure its future as a permanent memorial.

The goal is to establish an endowment capable of supporting the lights, which costs up to $500,000 each year.
