Everywhere I look, I find people arguing that folks should buy gold and silver, because in hard times, you'll need a medium of exchange.
A few weeks ago, I went to the feed store and traded 3 roosters for a 50lb bag of feed.
Last Saturday, I went back, and the gal working there hurried out to see what I brought. This time she traded me two 50 lb bags of feed for three roosters.
Now I have surplus feed, and fewer mouths eating it all.
