More than one wife is too much crazy to have to deal with...just sayin.
I like the mormon ethic vis a vis being prepared. I have lived 40 miles outside the closest city for 30 years and have plenty of long term food/water, plus replenishable water supplies and the means to defend them. Though I don't "worry" about the SHTF, massive upheaval, or whatever disaster du jour is going to happen tomorrow (or not). Worry leads to bad decisions in my opinion, so just have your poop in a group and relax. Whatever will happen, or not happen is going to happen, or not happen. Deal with it as it comes up.
