I agree with Byte, just late in getting into this thread to post my response. In a SHTF scenario, the person without a gun is the least of your worries. The person with a gun (even if they just got it from you in fair trade) is your most immediate threat to your survival. To arm someone else is an unacceptable risk unless they are someone I already trust with my life.
This is already starting. Crude went up over $80 earlier this week. with an expectation of it going through the roof. Too bad the U.S. doesn't have direct access to major petroleum resources in places like, say, North/South Dakota or a desolate section of Alaska's ANWR. If such resources existed, and our government would get out of it's own way, we could end our dependance on OPEC.
So, just be prepared to bake a dozen loaves of bread if/when SHTF and take 'em to your bank to pay off the loans.
