You don't need a book, you just have look around and see what people are buying. Gold and farmland, and if you're poor, silver and a cheap rural property near or in town. The Bushes are big in farmland, so is gates as we have just seen, and many others if you dig. All the world's central banks are stuffed with gold, Russia now holds more gold than it holds $US, and plenty of millionaires have come out saying they are investors. Don't listen to mouthpieces like Buffet, he's an establishment shill and only good as a contrary indicator. You won't know what those sort of people are doing until long after the dust has settled and the money has been made.
