I already talked about my BOB being my BTH (Bug to Home) bag where I plan on hunkering down if things go south. So generally I always have SOMETHING to eat in my truck and the random water bottles rolling around on the floorboards. That said, at my Bug Out Spot #1 I have north of 30 days of canned/dried food. Exclusive to that is 2 pails of the 24 days each freeze dried “Mountain House type” disaster buckets. Just nice to have in separate parts of the house. Veggies, Ram-men, Rice, Noodles, Tuna and my favorite Chef Boy-R-Dee Mini Ravioli (although I will admit that the Aldi’s brand is VERY good and I pick them up at 1/3’d the cost of CB-R-D). Because I am also a foodie I have more spices than you can shake a stick at so I can make chunk chicken in water taste good.
When I bought my house it had a dysfunctional well, the pump worked but it would loose the suction head in a matter of days. Spent the money got it re-shot (I think that is the right term) deeper and added a hand crank priming valve with ball valves on the go’z inta and go’z outa side of things. It’s not fun but I can hand crank my priming pump to the tune of 3 gal/ min with no power and lock it down so as not to loose suction.
Water is your #1 concern. Figure out how to get it and lots of it and you will live.
