Don't you have enough knowledge to "build" a pile of corn?  The market is telling you in very plain language that it wants corn "later" not "sooner."  The magic thing is that "sooner" corn turns into "later" corn all by itself if you just let it sit around for a little while. 

There's a reason all of us out here in never-never land have big galvanized metal cans setting all over on our farm yards.
