I didn't get that the food storage centers were open to non-members though, as this article says .
They sounded like a resource worth checking out as they have all the equipment needed, and will teach one the proper way to do it.
All in all, I ended up reading a lot of the website, and their family welfare system sounds like what a lot of churches should be doing in terms of taking care of each other (-not to denigrate anyone's church-maybe they do and I just don't know it).
They had a page on the sanctity of the family that was really touching, and once a month all members have a two-meal fast, the proceeds of which are donated to help other families. Neat.
The fast offerings on the first Sunday of the month provide a local source of cash for the Bishop of each ward to assist families that are struggling to make ends meet. Often those families have unemployment problems. In exchange for that help, they often assist with simple tasks at the ward building e.g. vacuuming, dusting, tending to the landscaping. The Bishop can offer cash or send them down to the Bishop's Storehouse to pick up necessary groceries.
I hope your visit to the web pages provided some useful guidelines and resources. Being prepared is a constant process. If you keep doing a little bit, it isn't much of a burden to accomplish your objectives.
