Yeah, the mix definitely seems ideal.
Hey, I discovered this site a few weeks ago and have been looking through it. I saw that you aren’t fans of bottled water, but it seemed like a strong choice to me, and I wanted to run my ideas out there and see if they’re very off base. 1.) Stores well: 24 packs of half liter bottles are easy to stack and transport.2.) Different failure mode than large containers: if you’re in an earthquake or tornado zone, a single violent even could pierce one of your 5 gallon containers and compromise all of its contents in one go. Such an even is very unlikely to destroy a bunch of plastic bottles, even if it breaks a few (a mix between different storage types, as you suggest, seems strongest here).3.) Easy to pass on to neighbors in need: If you have extra water based on the level of emergency, or if you’re simply willing to give up some previous stash in the interest of your fellow man, to preserve peace, or to trade for something else, bottled water is easily transferable without the receiver needing his own receptacle and doesn’t scream “this guys has lots more in his basement”.
