FEMA recommends making an emergency bag with supplies you might need if you had to quickly evacuate in the event of an emergency. Here are several ways to do that.
Survivalists have been on this concept for decades and have taken the art of making a Bug Out Bag (B.O.B.) or Get Out of Dodge bag (G.O.O.D. or G.O.D.) to a whole new level. I like the latter phrase less because the fundie survivalists seem to favor it, and Get Out Of Dodge Yesterday (G.O.O.D.Y.) bag would fit better. :)
My wife, who has only come over to my ‘dark side’ since the disaster in Japan, has instructed me to make sure ours is fully outfitted after the next paycheck. I’ve already been working on it, but with full budget approval from the better half I can make it GREAT! Now I can make one for each of our vehicles, and several for our home, including the kids.
What you pick will depend on your budget, but try to get the basics in there first. Alleviate disaster anxiety - prepare well.
