NEW YORK (WABC) -- This weekend, a thousand people will take on an ambitious task for a good cause.
They will climb to the top of the One World Trade, to raise money for the "Tunnel to Towers Foundation".
The foundation helps the families of fallen heroes.
Eyewitness News Meteorologist Amy Freeze talked with a widow of a fallen firefighter, who has always supported the cause and now is thankful for their support.
