jwfacts - I can see biblical parallels being drawn in the near future (in publications maybe but most obviously in talks) about leaving Brooklyn with Lot leaving Sodom, Moses leaving Egypt, 1st century Christians leaving Jerusalem...
Perhaps a 'vital lesson' will be taught about this process to the faithful - the GB and 'Bethel family' have left their home of 100 years in order to pursue 'kingdom interests'. What a fine example for all publishers to follow!!
I don't know of an underground shelter - but I do know that they'll have workout rooms, pool, tennis courts and walking/biking trails, picnic areas. The site includes a decent size lake as well.
Swank!
