You should see the response I get from people who tell me that I should to invest in gold like they did...
I look them straight in the eye and ask them how many of my eggs or chicken or vegetables they think they would get for their gold - Can’t eat it... Now bring me a side of smoked bacon or a nice ham, and I’ll bet we can strike up a deal. A really good one too.
I'm figuring on fair means of trade being food, meds, tools, utensils etc to barter. And the only other means of trade would be work. Now the unfair means of trade (okay not really "trade") will have to be taken care of by our stores of ammo. Which won't be available for barter. Only way anyone will get that will be at high velocity.
