Do you ever take ANY road trips? There is an awful lot of territory in the US that can be pretty desolate.
My "in" was winter driving. When we go up to the mountains. You never know when things may get very bad very quickly. You may get stuck in a storm or loose control of your vehicle getting it stuck or disabled in a very inconvenient location. Best to have enough gear to sit out any storm and make it back to get help.
From there, we also had some dicsussions about this bad flu season and the potential for some form of future pandemic. Those do seem to be somewhat periodic. It really is likely only a matter of time, just like the next big earthquake in Northern California. Only a pandemic would likely be world-wide and cripple the global economy for a period of time.
So, I have a BOB/GHB that would be good for several days (still some tweaking to do) and have started on storing up some home supplies (flour and sugar so far, and we keep a good amount of meat in the deep freezer vacuum sealed). Still need dried beans (protein), water, i bit more salt, and probably a selection of freeze-dried foods and vitamin C (if fruits become scarce, scurvy could be a problem).
