Speaking of stocking up on the essentials. I remember back in the early 70's during the 1975 craze some JW's in my Congregation were rolling up Watchtowers and putting them in plastic dish soap bottles and burying them in their back yard for use during the tribulation when the literature was "banned".
There was even a demonstration on how to do this.
That was almost 50 years ago and those JW's from my Congregation are long gone. I imagine one day there'll be an assembly experience where someone will be relating how they came into "the Truth".
"A few years ago I moved into a house and I was working in the garden and found a Watchtower buried in a plastic bottle and I immediately knew I had found "the Truth !!" (applause)
