I forgot to ask. What are you preparing for? The end of Aces High?
No way. AH can't end.
Where I live, there are things that should be considered, and no one will call you a kook for considering them: large earthquakes, tsunamis, (magnitude 9+ is possible and has happened along the coast of the Pacific Northwest), large volcanoes (St. Helens, Rainier, Hood, Baker -- lots of big volcanoes around here), storms that do things like knock out electricity for 750,000 people at a time (the last one put my parents and their area out of power for more than 2 weeks -- if that happened along with travel problems because of snow at same time, you'd be glad to have supplies).
Then there are the ones where, if you want to take them into consideration, some people think you are a kook, such as EMP attack or large solar flare that takes out electricity in huge area, some other act of war, economic/civil disruption that is large enough, etc.
I estimate that the odds of me needing stored food are very low, which is why if it's costly or too much work, I likely wouldn't get to it. But if stored food takes me a few days of work once every 30 years and costs $1-2 per man-day of food, I can manage that.
It's cheap and easy enough for me to have this insurance for my family just in case.
