If you have 14% 60 lb corn and 17% 52 lb corn and you are taking dock on it it's just because you are too lazy to blend it.  That's not anybody else's fault.

When everyone was bitching and moaning about $900 NH3, the price at the refinery was under $400.  There is nothing keeping farmers from buying it at that price and handling it themselves....but many seemed to think they had some sort of duty to cover the spec losses which were incurred by the guy who bought it and held it while it went down, instead of buying it at the current price....or else maybe they don't want to invest the money to set up bulk storage and do the work to run it....if so, fine but don't bitch at the guy who is willing to put in the investment and effort if he wants to make as much money at it as you will let him.   

If you think farming is more competitive then trucking, you've obviously never ran a truck.  We own five of them and practically never run them past the farm bins, because there's always someone else out there who will run cheaper then I can.
