The additional 20 cents per gallon is because the proper infrastructure for ethanel is NOT in place. It must be transported by truck or rail car and not by pipeline,,because of its vapor point. (For you know who,,,that means evaporation)...the govt MANDATED IT,,without having proper transport for it.
Best estimates (by people a heck of a lot smarter than me...and DEFINETLY smarter than you-know-who) estimate that the ethanol costs will be even 20 cents higher by the end of the summer. CAPICE?
