I'm posing this question to you guys because you are the most intelligent group I've come across regarding Peak Oil, investing and the economy. My close friend has been preparing for peak oil with the standard preps, is debt free, lives below his means etc... However, he doesn't believe that being and staying diversifed, regardless of what you "think" will happen, is the safer way to go. He wants to be mostly cash (age 37) rather than have and maintain an even percentage of cash, bonds, tips, gold, silver, stocks, reits (doesn't own any shelter).
