I have news for you all.  If this turns into an actual depression and then into
anarchy there will be very little you can do.  The population density in most
of the country is way to high to live off the land.  The cities would become 
battle grounds and the exodus would spread armed gangs into the country.
We all should have at least a 6 months supply of food, even if it's lots of rice
and canned beans.  Medical supply and vitamins to supplement our diets
would be important too.  Fuel, such as firewood, propane, and diesel should
be kept on hand too, as well as firearms.
Farm animals, especially backyard flocks, would become prime targets for
thieves.  Protecting these flocks would be close to impossible, especially if
free ranging.
But this is all just fiction anyways.  This downturn in the economy shall pass.
These depression posts are nothing more than depressing.  Have faith people.
