Hey everyone. I'm seeking answers and advice on long term survival in an TEOTWAWKI situation. I'll be doing a series of threads on various aspects of this and all responses are welcomed and I thank you in advance for your help and guidance. This thread concerns long term food and water. I have three deluxe one year supply of long term foods in # 10 cans here at the ranch, but even supplementing with the gardens, live stock and hunting it will go fast feeding the hands and thier familes as well as my "family".
So let's switch it to a cabin with a full size basement I own in the mountains. I have 25 acres to garden, raise basic stock and bees.

Here are my questions:

Water
How much should I store per person?
How should it be treated for storage and should it be treated or filtered before consumption?
In containers I am considering powerade bottles, 2-3 liter soda bottles, 5 gallon water jugs and 55 gallon water barrels, any thoughts on this?

Food
I've never tried the long term foods but the manufacturers claim they have a 20 year shelf life.
Would they be edible beyond that time?
How do they taste and are they filling? When I looked at Weiss I think it was, a daily ration was one serving of one half a cup of food.
What about grains? What should I store, how should it be stored, and for how long?
What are your opinions on survival type gardens? Are they worth the unwanted attention they might attract?

Again, I thank you for your help. And encourage any thoughts, comments and suggestions you have, even if they are off subject.
