Food Storage.

So how many of us would have the means to to feed our families if there was a food shortage or food became so expensive that we could not afford to purchase enough to feed our families. Shannon (my wife) and I have been talking about this over the last couple of days.  Let's face it if it can happen with gas why could it not happen with food.  It's just as important as gas is it not?  I know that some maybe saying, but we depend on other countries for our gas and not our food. By all means I'm not an expert at all but looking at what's happening with our food.  Not too long ago our lettuce and spinach were bad because of salmonella and now our tomatoes are the same way.  What about our grain.  I assume and again I'm not an expert but I would assume that the majority of our grain comes from the mid west. We all know that they are under water and the crops are gone because of the flood waters.  I feel that because we have not gotten some food that can be stored now is the time to try to get as much as possible.  That way we are prepared for what ever may happen.  If the food prices start to go up like gas then we maybe able to keep our cost down because we can us the food that we have saved.  If the prices don't go up then we have some food storage if I happen to lose our job or some other disaster that could happen.
