I haven't gotten into it literally due to a major lack of funds, but I tell you if I had extra money to blow, especially if I won some crazy amount of money in the lottery, I would be a HUGE prepper! I'm talking all out. I would move somewhere remote with lots of land, my own water supply, a massive underground bunker, 5yrs+ of stored food, gold and silver for trading, and of course LOTS and LOTS of guns and ammo!
Now I'm not 100% convinced something devastating will happen at the end of 2012 but I gotta tell you I will not be suprised one bit if it does. I'm more concerned with the economy and value of the dollar collapsing. Can you imagine if we have another stock market crash like in the 20's? Things will be worse now 10 fold or more. It will be total anarchy, a complete collapse of the system and when people start starving you can bet they will get savagely desperate. Another scenerio I worry about would be a massive solar flare, which we're supposed to get in 2019. How will you deal with everyday life when every single piece of electronics in your life is suddenly gone? No heat, water, electricity, cell phones, gps, television...everything worthless. Much like a 2nd great depression, things will turn ugly very quickly.
I'm really hoping the world holds together for another 8-10yrs, cuz my soon to be wife is in school to become an RN within a few years and then move forward to a nurse practioner. And once she starts making the big bux is when we start prepping in a big way!
