I remember back in 2008 when I was dating the woman who I'd later marry. Whenever I'd stay over at her parents house I'd be in the spare room which was literally a stockpile on bags of pasta, rice, tinned food and bottled water.
10 years later, the world is still here and all that food must have gone off by now.
Some entrepreneurial JW nut is even selling go bags to JWs on his website.

I love how, on their offical website, on a list of essential items the bible is even on there... right at the bottom.
