For just a room in your house that you want to hide in for a while should something bad happen? Okay, here’s some thoughts:
Can’t have too much water.
Feminine hygiene products.
A knife. Or multi-plier thing.
Work gloves. Work clothes, summer and winter.
Chap stick. Seems whenever I’m stuck somewhere that I get chapped lips.
Mattresses, sleeping bags, blankets, sheets.
Scrabble Board or some other game for you and your fellow survivors to while away the time with.
Books, preferably short story anthologies (anything that drives you into a “safe room” is going to detract from your attention span). Boredom’s a killer.
You’ll need a guitar or harmonica or something.
Whatever you pack in your toiletry bag when you go on trips (toothbrush, soap, etc.).
What are your kids going to do in the hours, days, weeks, months it takes for the National Guard to find you? Got coloring books and kids games? Got something tastier than MREs for them to eat?
Got a dog or cat you love? Thought of his or her needs? You may need dog food or a litter box or something.
Religious? If so, you’ll want a Bible (or whatever) with you. If you’re stuck in your safe room, scared, and alone for a long time, you’ll definitely want to turn to your higher power.
Tons of batteries. All sizes. You don’t have enough.
Your tool box and first aid kit is not complete right now, I promise. And whatever you don’t have is exactly what you’ll need.
Plastic bags to dispose of human waste. And leftover food for that matter . . . you really don’t want to be overrun by rodents, and it takes rodents no time flat to overrun a place.
Mouse traps. Rat traps.
There are alarms for chemical warfare agents–-I don’t know if they’re available to civilians (hell, they’re not even available in proper numbers for the military according to a news report I saw the other night), but if you can lay your hands on one it would be beneficial to you.
Medicine of all kinds. Every kind of first aid equipment you can lay your hands on.
Got any addictions? I know there was a time when I wouldn’t have been able to handle The End of Civilization without cigarettes.
Knowledge. Make sure you know how to use your rifles, IV’s, generator, or whatever before you need them.
Hell, I don’t know . . . how much money do you have to spend? How long are you gonna be in this place? How crazy can we get with the scenarios? If I were you, I would go to your local Army-Navy Surplus and Hunting/Camping supply stores and browse around for ideas. It also wouldn’t hurt to brainstorm with the people who you think will be your fellow survivors. Remember, everything you need to do in your normal daily life will be something you will need to do in your post-apocalyptic life as well.
