Amid misty waterfalls and art museums along the parkway where Pope Francis will hold a public Mass in Philadelphia Sunday, makeshift abodes belonging to some of the city's homeless are coming down.

Benjamin Franklin Parkway, a stretch of cultural centers and grassy parks where homeless sleep and tote their belongings in plastic bags, is undergoing papal security checks and cleanup that will displace some of the downtrodden that Francis champions.

"With this papal visit, I've got nowhere to stay," said Joe Flatley, 52, a former corporate sales manager with an alcohol addiction who sometimes sleeps in the parkway.
