I recently did a preparedness spreadsheet which inventoried all of the preparedness items I could think of in my Bug in closet and bug out bag. I have been focusing on solutions for getting water and holding water when I realized the value in figuring out what empty vessels I could easily deploy in an emergency situation with a bit of warning or without.
I now have identified and itemized all larger empty containers- igloo drink cooler, canning pots, 5 gallon buckets etc. I realize that knowing where I will get my water from is only task 1. Staging it in containers that fit the task will be next on the list.
That way I won't have to touch my rotated/bottled water stock first thing, and maybe not for days I thought about what pots I would consider boiling water in. I considered what water I would use for sanitation, for cleaning and save the higher valued water for cooking and drinking.
I did the same thing with my "cooking" options, all the way from a "dutch over over fire", to propane campstove, white gas campstove, charcoal BBQ, sterno and chafing dishes, and even an old "shabu shabu" japanese charcoal cooking pot that could be used in a pinch. Bad news is I have 6 different cooking fuels and systems. Good news is I have 6 different cooking systems. I have randomly been increasing my fuel stockpiles for each.
Sounds like small bottles of propoane are a high demand item, eh?
