Kinda strange. According to some stuff I've found, as late at October of '05, these folks may have still been there - or at least speaking in relation to the University there:
"October 28, 2005 -- Under the auspices of The International Qur’anic Open University at Islamberg, New York, USA, a volunteer team of doctors, nurses and medical technicians departed from John F. Kennedy Airport October 23 and arrived in Islamabad, Pakistan."
Also sent some of their folks south to help with Katrina.
Doesnt say how many, but from my understanding that place "was" supposed to have housed over 300 within the "community" in Islamberg.
Seeing that they've mentioned that the Feds were actually in contact, and the reports mentioned all over the net perhaps they've moved south to the Virginia or Carolina based locations.
What I do wonder is this: 70 acres and no-one is there but the two who approached the reporter - then where the hell did everyone else go????
