NEW YORK - AUGUST 28: A worker looks at one of the first Swamp White Oak trees planted around the Memorial Plaza following a ceremony at Ground Zero on August 28, 2010 in New York City. The trees were chosen from areas within a 500-mile radius of the World Trade Center site, including New York, Pennsylvania and near Washington D.C. to symbolize the locations directly impacted by the 9/11 attacks.

An anonymous benefactor stuffed $10,000 in cash into a 9/11 donation box at the World Trade Center.
The box hangs on a wall at the 9/11 memorial preview site. Memorial officials believe the money was slipped into the box sometime between 5 p.m. -- when the box was last checked -- and 7 p.m., when the preview site closed.
Officials believe the donation was made by a single person. They say the bills appeared to have been recently withdrawn from the bank.
Daniels said officials would love to know the donor's name so they could say thank you.
