Pope will make first US visit in April

He'll visit Ground Zero, the White House, the United Nations and say Mass in DC and at NY in Yankee Stadium.

"Benedict will travel to Washington and New York from April 15-20, speak at the United Nations on April 18 and visit ground zero on the final day of his trip.
...
The visit will take place on the third anniversary of Benedict's election to succeed Pope John Paul II, who died in April 2005.
An official welcome reception for Benedict will be held at the White House on April 16, Sambi said. The pontiff will celebrate two public Masses, first at the new National Stadium in Washington on April 17, and again at Yankee Stadium on April 20.
He will also hold meetings with priests, Catholic university presidents, diocesan educators and young people."
