Catholic News Service has provided us with the latest update:
More information will be made available after January 1st at the Web sites of the Archdiocese of Washington and the Archdiocese of New York. Also check back here for the latest updates.
Pretty much the only chances the general public will have will be at Masses at the Washington Nationals' new baseball stadium, with a capacity of about 45,000, and Yankee Stadium in New York, which has a capacity of perhaps 65,000.
The youths and seminarians rally at New York's St. Joseph's Seminary also is listed as a public event, but Joseph Zwilling, communications director for the New York Archdiocese, told Catholic News Service the 15,000 to 20,000 spots will be filled primarily with people from the New York region and some of the approximately 5,000 seminarians in the country.
... Also yet to be decided in both cities is whether the pope will have a motorcade route where people may line up for a chance to see him, said Zwilling and Gibbs.
