Thanks, Larry for the assumptions. Did you mean the link to the Coallition for Ethanol website (what were you saying about agendas?) or the one with the happy sun shinning over the cartoon depiction of environmentally-friendly ethanol production that seemed to leave out a few key steps?
here's a few links (not without agendas, but informative, neverless):

I guess the pros and cons depend on who you ask, and their agenda.
As for mine, yes, Mr. Griffin, it is quite old. Concern for the planet and fellow humans doesn't go out of style.
