Don't keep all your eggs in one basket if possible, Natural diasters are famious for the home fires that follow! Got Natural Gas? When I lived in Lancaster,Ca. I could spit on on fault line, My block actually had a agreement, if stuff started shaking, we would shut of the gas at the meters. Bug out bags per family member is a cool thing, Got to figure out if your a go person or stay person, Physical ability etc... What about Gas mask??? Before you die laughing, try holding your breath, and remember if in riot zones CS gas sucks! Dirty bombs, if you got to leave to get someone, not breathing Beta particles would help, their dirt cheap now. Ever try shooting your must have rifle in a mask. If the unfriendlys get some tear gas grenades, your holed up, and you let the scum get close enough to throw something in your nice plate glass window. Get ready to puke,cough,puke. Its the one thing I never see on any list, and its the first thing Israel, has for everybody, Whats up with that. Even a train derailment or chemical plant problem from miles away could really hurt, just nature and human stupidity can cause needs for a mask, and now we live in times where radation,chemical or Bio agents are available, and lots of reports of missing stockpiles from the old bear, who is waking up again and starting to feed. Ladies and Gentile men get a mask, if you don't need them, on your death bed, will them to some pot heads, they have fun with them. Water purification for on the road, communication, and rally points are good things to remember.
