Joshua Fattal held an "Occupy" inspired event in New York yesterday.
The 30-year-old from Elkins Park and his two friends were taken into custody on a hiking trip.
They spent two years in captivity because officials in Iran thought they were spies.
"I'm feeling really good, I mean obviously I'm just feeling good, but it's not easy to transition. It's really not easy. A lot of people experience trauma, but mine was very prolonged, systematic, enduring trauma and it's hard to come out of that," Fattal said.
Fattal and the other hikers are working on a tell-all book to be released next year.
