We LDS people have been taught to have a one year's supply of food and necessities of life. We must think about feminine hygiene products as well. Here is someone who is talking about this subject.
Patriot Nurse is not LDS, as far as I know. She is a "prepper", someone who prepares for the worst case scenario. ("Prepper" is the new term for "survivalist".) So you may not understand some of her terminology.
"Bugging Out" means evacuating from high population areas to somewhere safer, such as a fortified location.
"When Poop hits the fan"- thats what she says instead of the usual Prepper phrase, when "stuff" hits the fan, or SHTF.
I know it isn't pleasant to think about a scenario where we will not be able to go to the store to buy tampons and pads, but remember President Kimball's statement:
"I remember when the sisters used to say, 'Well, but we could buy it at the store a lot cheaper than we can put it up.' But that isn't quite the answer, is it?....Because there will come a time when there isn't any store." (April 1974 Welfare Session.)
