Actually....I don't think this is that cultish at all(well, not too much).
I think they want to be away from any bad publicity that their social ineptness causes like on 9/11.
Out in the middle of nowhere there really isn't many people to turn away if a disaster strikes.
Plus I think if they can get a good price for their Brooklyn properties and build for less, why not?
They will probably need all that extra money to pay off settlements anyways.
I just wonder if they are going to find a way to make the congregations pay for it while keeping the Brooklyn money.
