Hmmmmm that's a tough question. I would have to say it was the natural conclusion to a lot of research.

Well I grew up in a off the grid farmsted/ranch. After seeing what war does to a country and its people, while I have servered with our military and in other countries working a "secuirty" job outside of the military no matter the country be it war or acked of nature. People are always the same... As for the how. I'm working at my stocks, and skills. I am trying to expand my skillset in the medical field from tactical to Surgical and care giving. Also my mechanical skills and machining parts and tools. Maybe I can last a year right now but thats not good enough 😎

Seriously into prepping? after the 2010-11 floods here in Qld, most of my family was either cut off from home for a bit, nearly swept away, or in the case of my parents forced to go to relatives due to power out for 5 days. myself and one brothers family were barely affected aside from in a general sense.
As I depend on grocery delivery services which were suspended due to unsafe conditions on the roads, I was a little short on supllies. this got me looking at being more ready.. I had basics (many thunderstorms here), but I started researching, and stocking up, and learning.

the ice storm for me. we were lucky we had a generator and a wood stove.. now we are prepping for the longer outages.
