Why is it

[Nephew Twiddleton]

I think he refers to the mandate that all Mormons keep a 6 month food supply on hand, just in case.

Just in case what? Accidentally have 4 more kids?

That would require a couple more wives and then even more food on hand.....

It's a terrible cycle they really should try to get out of.

The locals burn down the temple and they all have to flee across the country on foot again?

It's an old rule, from when Mormons were a major target of angry mobs and the government.  Outside of earthquake prep it's not worth much these days.

Ah. That makes sense 150 years ago.
