In my opinion, the best solution is to set up our own safe houses in case any one of our homes becomes unlivable do to disaster (single wall houses). We all know the recommended evacuation zones are deathtraps of plate glass. We either take care of each other and our own or we are worthless pieces of shit.
Assume folks will have very different plans based on their circumstances (yeah, thanks Capt Obvious
). For me, I sort of have a series of "safehouses" with family where I have either encouraged that household stock up on stuff or flat out got some stuff for them. That includes stuff like water, medical supplies, etc. Sure, I have close friends where we've discussed stuff like "if X happens, I'll come over your place with Y" and vice versa. While I do think contingencies with close friends are good, in my case, I am more depending on the contingencies with family. There was a thread a while back on how would one react in the case where the individual has taken time and spent money investing in preps and how they would handle friends and family assistance. It was an interesting discussion, but the point I was getting to is that I think a lot of the "preplanning" goes out the window depending on the disaster event. Like those books like Lights Out and the ones about EMPs have some eye/mind opening stories in that regard. People tend to envision a certain scenario and prepare for that, which is logical given we all don't have unlimited resources. But a saying that a mentor shared with me a while back always stuck with me is that "95% of the time, it's what you don't see coming that will kick your ass".
