Before heading back home, Pope Francis had traveled more than 7,000 miles in nine days. Impressive, but not quite as far as a family from his home country who made an epic road trip to see him.
They left Argentina in a VW bus named Francesca. Catire Walker, Noel Zemborain and their four children set off from Buenos Aires for a 13,000-mile pilgrimage.
Mom and dad quit their jobs and used savings and donations to fund the trip through the Americas -- crossing 12 borders and staying with dozens of host families.
On the way, they saw the sights -- even the White House.
Francesca the bus had its share of breakdowns...but the family pressed on.
Finally in Philadelphia, their dream came true: all six were granted an audience with Pope Francis.
"Are you the family who traveled from Buenos Aires? You are crazy!," Pope Francis said to the family with a laugh.
There were hugs -- and then he said, "I need your prayers."
Vatican spokesman Father Lombardi made a note of the visit.
"The meet with the family touched him very, very much," Lombardi said.
