Pope Trip: "Bush to greet pope at airport in unusual gesture"

AP:

Pope Benedict XVI will be greeted by President Bush at Andrews Air Force Base next month at the start of the pontiff's weeklong U.S. trip, the Vatican said Monday.

... The president traditionally greets visitors at the White House. The most elaborate welcome has been a South Lawn ceremony with trumpet salutes, booming cannons and the Old Guard Fife and Drum Corps, dressed in 18th-century uniform, parading by the reviewing stand and invited guests.

Does anyone know where John Paul II was greeted when he visited the United States each time?
