You'll have those whack jobs out there everywhere. They've been out there for years. These are usually the first people to run to the gas station and stock up when the price goes up. I remember seeing people with 55 gallon drums at the station on 9/11.
Y2K, SARS, etc. Oil is the new reason to stock up and arm.
