I have to admit that I do enjoy storing distilled alcohol products because they never go bad and I look forward to consuming them at some point.
Have you considered acquiring/building a Still? You can legally use one if you get a small fuel producer license from the Feds. You have to denature the alcohol for use as fuel of course.
I have got to get going on water, too. I have a 50 gallon storage tank (most people do in the form of the water heater) but I am going to eventually have about 500 gallons of drinking water on site. Also have a super water filter on my list. We live in an area where there are streams and lakes plus there is snow on the ground a lot of the year so filtration needs to be part of the strategy.
Don't you have a well? Giardia is not something you can afford to mess with come Teotwawki. Yes, you can filter the water. But typically this means collecting it from those original sources..meaning its on your hands, on your shoes, etc.. If you keep the filter away from those places and can bring the water to it, it helps, but contamination during the backwash to clean the filter, or just from your hands etc touching it it a real concern - especially as the morons around you start deciding that the stream is a wonderful place to dump their sewage. Make dang sure you have lots of disinfectant on hand. -- The stuff you disinfect your still with is probably a good choice..
Then there is the actual security problem involved in going to collect the water and walking back without being shot.
Further, with no well, what are you going to do with your own waste? Dig a latrine? Maybe I am just old and lazy, but I can't deal with that crap when I need to be focused on what the bad guys are doing. It sounds like you are doing great on the food stores, but having reliable water and power would be next on my list - even it that just means an illegal well , a solar well pump and a cistern. If you are going to be spending money, it does make sense that you are using it to produce long term solutions - not a stop gap that will provide you and extra month or two.
If this breaks into a civil war, it is going to look like Bosnia. Utilities will be under attack and unreliable if available at all.
If its an economic collapse only, it won't be as bad, but if you are rural, they are not going to pay to maintain the utilities out there. They will run them till they break and then quit (no federal grant money or enforcement laws to force them to provide you know) Rural areas will get infrequent food and supply deliveries for the same reason. (this is how Michelle convinced me that an in town place may be prudent- we have a rural place to go to if town becomes untenable, but town is where supplies and some semblance of law and order will be if it exists at all) Either way, foodstuffs and supplies to resupply with etc will become more expensive and harder to obtain. This is going to last YEARS and YEARS and I think that is the time frame you need to be planning for.
