Center city is locked down. Metal detectors are up at the most secure perimeters and barricades are blocking vehicle traffic. Out of towners are pouring in and ready for the Pontiff’s visit. This group of more than 100 came all the way from Phoenix.

“Really excited,” said one woman.

“It’s really exciting for me because I’ve visited the Pope a couple times already,” said another woman.

The National Guardsmen are at their posts at nearly every corner.  With tighter security in Philadelphia than New York and Washington, D.C., CBS 3 Eyewitness News asked the Pennsylvania Governor Tom Wolf if the extensive measures will be keeping away the faithful.

“The other cities didn’t have the open events that we have here,” said Gov. Wolf.

“That’s a balancing act, you can’t just sort of throw things open and hope it works out, you got to do some planning,” said the Governor.

The Governor will greet the Pope when he lands Saturday and be in attendance at his masses.

“The proof’s in the pudding but we’ve done everything we can to make this a safe visit, but also a pleasant one for the people who are here,” said Gov. Wolf.

Volunteers Anne and Nora say the measures are well worth it.

“We need the security because you don’t know what’s around the corner,” said Anne.

“Watching it on TV Washington and New York, it really gets you more excited,” said Nora.

Expected crowds or not, the street vendors are cashing in selling memorabilia and even a selfie with Pope Francis.
