This is not the year to be worrying about quality. Get it out! Put your round bar concaves in and go! It's worth more to you out ASAP than it is holding off and hoping it will dry so the sample improves.
The losers will be those who don't bite the bullet and start harvesting the entire crop as high moisture ASAP. At this point, there is no corn crop within shouting distance of the entire midwestern corn belt that is going to be any drier than it is right now. Why wait?
If I didn't already have an entire fleet of tracked equipment, I would be out purchasing an older secondary fleet of machines (tractors, combines and grain carts) on tracks to get out what I can and start custom harvesting once I am done. Because you know there are those who think that it is going to get better.
