I know a lot of guys who still went out and shelled what corn they had, even if they did it at a net loss. Farming is a point of pride. If there's only 50 bushels out there, they'll get it in the bin, come hell or high water. Not the most practical, business wise, but it's good to know there's still some people out there like that.
I would also like to point out that most federal crop insurance programs are revenue based, not strictly on yield. Most insure crops at the 80% level or less, so insurance paying off better than a good year is highly unlikely. There have been a few mediocre years, where I thought a good hail storm would come in handy, but most of us would rather have a crop we can brag about in the end. Also, don't forget all of those years we paid our premiums and didn't make any claims. The system we have might not be perfect, but it keeps food cheap.
One other tidbit that might be interesting - a lot of grain had aflatoxin in it last year, which has gotten worse in storage. Many elevators are now stuck with excess inventory they can't move until they start getting clean grain next fall, so they can blend it out. I'm really not sure what impact this will have on prices, but it could get interesting...
