Day Nine: Indiana to Chicago

We left at 6:30 am on the first leg to Chicago.

It was a visually interesting ride, if you like endless fields of corn and soy.  “Biofuels,” said Duff, with contempt.  I noticed many corn fields that had an almost pinkish shade in their dryness.  Also noticed variations of color in the soy plants that brought this odd question to mind:  Is there any chance that such vast acres of non-food crops are being watered with pollution perhaps not allowed when the land was used for food crops?  I know agribusiness is a chemical business, and I know the energy business is in many places related to the waste disposal business.  The question arose from my protective nature:  when the land is returned to feeding life, will the land still be good for food crops?
