I think our internal blending really goes to demand and where we are geographically and the customer's desire, because some customers desire to have the RIN attached, some do not. So it's not been a preponderance of our business. We tend to do more of that in the summer time because of the regional players, if you will, that we sell to. Certainly that would be a desire since that typically is the highest margin business that we have because we retain 100% of the RIN value. Back to your first question, Jon, on will the credit have an effect on RIN prices, there is two different issues there as I know you are aware. You have got the dollar blender credit and you have got RIN values and RIN values are directly in proportion to what production is going to be. So I think it would be a widely held view that there will be more production in the marketplace for that credit than less because it brings some of the players, I will call them inefficient players, back into the market place because they get that additional support from the government. So I think there would be, all things being equal, more production in marketplace maybe from the soy players. And the question really comes down to, do the fully integrated players come back in and those would be the ADMs, the Cargills, the Bunge's, do they come in. And the National Biodiesel Board will tell you that they produced about 300 million gallons last year and then came out of the market, and that looked to be to support the other side market on the soy oil, because I can't imagine that any of that production even fully integrated, was done profitably. So the question is, how much do they really come in. And I think there is a view on the marketplace that there is a reasonable chance that they are not going to be players because I think it's more economical for them to go to the other direction on the business. Without those fully integrated players in there, it's probably going to be reasonably hard for the industry to exceed 1.28 billion gallons. I think they can reach it but the question is, how late in the year and what are the economics due. So we have seen an acceleration in RIN prices this year. We closed out the year, Rose and Chris will know better than I, but let's call it $0.40 roughly, maybe a little higher than that. And they have gone to as high as $1.15, is the highest point I've seen this year, and this morning they sat at about $0.83. So 1.5 times that, it gets to be a real difference in profitability for this industry.
