This is good information, aside from the Zombies!! LOL
Here is CA we are all about preparedness...but our "boogey man" is earthquakes! One of our best ones is to fill your washing machine with cold water and put a little bleach into it. Just in case you need water in an emergency (like an earthquake!), it holds a lot. And you can then just put in a load of clothes the next time you wash, and then refill the washer after your laundry is all done.
