Is Oil Headed for $100 Shock?

My friend Len has been ringing the alarm bells on oil supply for quite some time and has been gloating lately about how right he has been about the prices going up. Now some people out there are warning of prices $100/barrel if this whole Iran mess escalates or anything else nasty happens. There's a lot of if'ing in the article, but who knows. It may be just as likely that oil will head towards $50, only to spike later. Still, it may be a good thing I don't own a car.
