Taking Metro is best bet in getting to papal Mass, by Richard Szczepanowski. Catholic Standard March 26, 2008:
To celebrate Pope Benedict XVI's historic visit here, Metro is offering a commemorative one-day "Mass Pass" that will give riders unlimited access to Metro all day on April 17.
"It will feature the event logo so it will be a great keepsake of this special day," Susan Gibbs, a spokesperson for the Archdiocese of Washington, said.
Metro will sell the one-day commemorative pass for $9.
[The diocese recommends that] Mass-goers purchase the "Mass Pass" in advance to avoid the long lines expected at farecard machines that day. To purchase passes, log on to wmata.com/onlinestore. Individuals and groups up to 22 persons can purchase on-line using a credit card. For groups larger than 22 people, call 202-962-5700 to place a bulk order.
