VATICAN CITY (June 17, 2013)--Pope Francis blessed thousands of Harley-Davidsons and their riders Sunday.
Thundering engines nearly drowned out the Latin recitation of the "Our Father" prayer that accompanied Francis as he greeted the crowd before Sunday Mass.
Standing in his open-top jeep, Francis drove up the main boulevard leading to St. Peter's Square.
The Harley riders were celebrating the manufacturer's 110th anniversary.
Once the service got under way, bikers in their trademark leather Harley vests sat in the square alongside nuns and tens of thousands of faithful Catholics who were taking part in an unrelated, two-day pro-life rally.
Francis addressed them both afterward, giving a blessing to the "numerous participants" of the Harley gathering.
Earlier in the week, Harley-Davidson gave the pope two white classic Harleys for the Vatican police force to use.
