it was generally accepted that grain prices didn't go up until the commercials owned most of it. 

That's because buyers didn't have to work very hard at it.  Easy being a grain buyer in the 80's.. all you needed was a phone.  Golly how much over loan am I gonna have to pay today.. 1..2..3..5 cents?

(golly hope Ray J doesn't see this.. he he.. we'll see if he's still reading this board.. I'm sure he'll have a comment. ;-)
