An anonymous donor has pledged a large sum to the Metro United Way if the agency can raise the same amount by month’s end.The United Way will get a $200 thousand matching grant if it’s able to generate the funds before 2008 comes to a close. Spokesperson Mark Zanni says he expects the organization to meet that goal.“Now is the most heavy time that we experience and so we should be able to easily reach that, not easily, but we should be able to reach that," he says.Zanni says so far this year, Metro United Way has raised $24 million.
