I am putting my bug out bag together, as the world is going to hell in a hand basket, and the post by WETSU has to be one of the best I've seen. I am going to use his recommendations a guide. Once I get this compiled, I will send some pics, for those that care. I used to think that a bug out bag was handy, but maybe not necessary, but now I believe its a must have for disaster survival.
I have family who recently evacuated their home due to flooding and weather and I'd be willing to bet they wish they'd have had something packed up so they could have grabbed it and left without any worries.
