I became a JW in 1973, everybody was caught up in the frenzy. There was a really nice family in the congregation that had inherited the family farm from his Dad. They sold it sometime around 1973-1974 and moved to "where the need was greater." (Southern Idaho, about three hundred miles from where we lived outside Pulllman, WA) He had calculated how much money he thought it would take to get to the New System and figured they'd come out just right.
A couple of years later they spent the last of the money and he had a nervous breakdown. I don't know what the family lived on.
