Good post fish n chips.
I would add that in any scenario where survival and/or relative comfortable living compared to not being prepared and living poorly is concerned, the three main issues are diversity, diversity, diversity. Not having ones eggs all in one basket, so to speak. Have many multiple ways of providing for ones self and family. With a pond and fish in the pond being one small portion of a much larger and more diversified plan. If a person is depending 90% on a pond to provide sustenance, that is an entirely different scenario than if it is 5% of "the plan".
I would guess in Griff's case, maybe the pond portion of "the plan" is more of the 5-10% of the prepping plan rather than it being the major portion of sustenance in the event it is needed because more normal channels have been made inoperable.
Would that be a safe assumption Griff?
