food stockpiles. I did recentley hear that stores such as Walmart rely on very quick turnover of goods these days and do not store large quantities of anything anymore.
So, if something catastrophic disrupted the flow of goods...we could all be sitting hungry in a hurry.

I guess this is a good reason to try to be self sufficeint and act on what the RedCross recommends-Storing enough water and food for a minimum of 3 days, but longer is better.
