I appreciate that. If you can give us a model we can go on there, it would be really instructive. I thank you very much.
Because Mr. Angelucci had some good comments here, I want to ask him about biodiesel. He talked about cost comparisons with natural gas, and the price gap between biodiesel and regular diesel—15¢ versus 3¢ is written here—but let me ask you this: Does this include the cost of excise taxes that are incumbent upon diesel and that aren't imposed on biodiesel?
