Thanks, Dr. Webb.
I want to turn to Mr. Walker now.
I know you talked about transportation. Eight union contracts with railways expire on December 31. Everything I've heard is that we could have our yields up about 50% compared to last year, which was admittedly a difficult year.
What impact has rail capacity had on our ability to meet some of our goals in terms of trade opportunities and moving goods? Is the industry potentially looking at what could be happening later on this year?
