Thank you.
I want to talk about agriculture for a minute, Mr. McCabe. You talked earlier about the opportunities in agriculture to use waste products for biofuel and bioenergy. I couldn't help but reflect on how historically the early settlers burned buffalo chips to keep warm in the winter, when we had bison across the land. We're going back to where we started from, I guess, in some ways. I wonder if you could talk a little bit about the opportunities you see for using waste agricultural products going forward.
