It's really a combination of prices and weather. Historically, if we have had good weather for planting and if prices are ahead of the average for the last few years, that has encouraged more corn acres.

Here in Iowa, there were a lot of nervous days during the summer due to hotter weather than in earlier years.

Delays from here on will further compound the lack of storage.

We just don't know how all of this is going to play out. We're hearing that when river and ports do open that it will just be during daylight hours because nighttime navigation equipment is out. That will cut shipping capacity by 50 percent.
