New York -- Even though the cleanup work at the World Trade Center is slow-going, there are more than enough volunteers and equipment. Organizers have been overwhelmed by an outpouring of generosity and many people wanting to help have been turned away. "There's nothing I can do but wait for my flight," said Sarah Patterson, whose offer to help out was turned down on Saturday outside a volunteer centre. The 32-year-old child-development worker at Toronto's Hospital for Sick Children, who has been trying to get back home since Tuesday's terrorist attack, had hoped to counsel children. Instead, "when we got here this afternoon, basically they said we could help give food to relief workers," she said.
