I can basically live off of homebrewed liquor and frozen pizza for months (only actual life skill college taught me) but if the crap hits the fan, It'd be better to have some better sustenance. I always have at least a 7day emergency supply on the ready, but I'd want to hear from you guys which one would be better if stuff goes real for a couple months. Also, do those solar water boilers work ? I'm thinking of getting one.
