Workers paste an image of the late Pope John Paul II to a giant billboard in Silao, Mexico, Thursday March 22, 2012. It's been a decade since the former pope visited Mexico; his fifth and final trip to the country. His successor, Pope Benedict XVI, arrives Friday, to a very different country and welcomed by a church that has suffered debilitating setbacks amidst sex abuse scandals and a lower percentage of Mexicans who call themselves Catholic today compared to a decade ago.
