Do your homework on ethanol.
I live in rural Iowa. I know farmers, worked for farmers, and have relatives that work in the Ag arena. Ethanol is all around me and I myself have been involved in added-value ag. I know more about ethanol than most people on this board.
And ethanol wasn’t even a factor till about 2000. Farmers stopped planting wheat here is substantial amounts in the early 90’s. We stopped getting enough snow to make a go of it. Farmers until then had been doing the bean-bean-wheat rotation since the 50’s. I saw it with my own eyes.
