Including OPEC to some extent. You might have a refinery in the Mediterranean basin that can only run Saudi Arabian crude. So it's willing to pay more than someone on the Gulf Coast of the United States for that kind of oil. It's a short haul crude, and it's perfect for your refinery. All this stuff works into a worldwide crude market, and in the end you have something that's almost incomprehensible.
Heating oil is a whole other story.
The heating oil guy will call you every year just before winter and say, if you want to buy your oil for the whole season I'll lock you in now for X dollars a gallon. And it's usually a quarter or something over the market. Two years ago, when the price went from a buck to 75 cents, maybe to 60 cents, these customers were all screaming. They signed the contracts, collected the premiums, and didn't actually have to pay for the hedges. Well, you've certainly given us a flavor of just how complicated it all is.
