Talk of an eight-foot security fence, long walks and no driving from river to river may prove to be too high a hurdle for some considering attending the Pope’s public events.

“I think there will be far more people who say ‘it is worth it’ and are willing to put up with whatever it takes than those who say that it isn’t.”

The Secret Service also doesn’t plan to reveal the exact street closures and the boundaries of the Papal security zone until early September.

“We would love to know everything,” says Levitz. “But I think we all have to accept that’s not going to happen. As one person told me, ‘Meryl, we’re the SECRET Service’.”

The absence of info may fuel rumors, but Levitz says right now no information is better than misinformation.
