I had a really good reply post ready and my 1984 garage computer crashed while I was trying to post it. Damn the bad luck, but it's absolute failure allows me to sum it up in a few lines instead of the novel I had. Having been through Hurricanes, Tornadoes, etc on the mainland, I thought I would chime in.
Like minded individuals will always group up together. Good or bad. Be skeptic and choose carefully. Keep your friends close and your enemies closer. Your best buds friendship no longer matters when he can't feed/water his family and you can....something has to give there.
The "majority" remains the majority when it comes to dealing with the loss of everything they are used to in their daily lives. They still expect the expected that will never come to them and most have no ability to improvise or even realize the predicament they may be in. When it gets bad, the GOV isn't coming to save you no matter how much money you have. This makes them dangerous....spoken riots, looting, and just down right stupidity.
In a real crisis, situational awareness, provisions, KNOWLEDGE coupled with the WILL TO SURVIVE are worth more than some beachfront property. If the US dollar suddenly became worthless , I like to think my mindset and doctrine is worth its weight in gold. I also think that stockpiling gold is stupid IMHO..if the shit goes down, I would rather have ammunition and stores than a pound of gold in my possession.
I have spent time living in the wild "off the land" and it is by no means easy; we barely made it on sticks and stones after 3 weeks. Even armed with the know-how and the tools of the trade , it is down right difficult by any measure.
Suddenly all the critters you think you will eat go on vacation, your water sources (the most needed of all) are not viable or reliable, your will to survive is easily tested after the loss of water, food, or shelter. If you cannot cannot provide water, food, and shelter, for you and you group, you will all be taking a dirt nap quickly.
IMHO, even the majority of "haves and have nots" eventually become the people at the shelter (avoid if possible) . It's the "can and wills" that will survive. You have to decide early to be in that group and have that mindset. You also need to arm yourself with the knowledge, and application thereof.
