It's not without its faults (what is?), but this is all very easy to control. My point with subsidies on ethanol production is, is that alot more good comes out of it. Farmers are getting busy again, any relief from the dependancy on foriegn oil (or any oil for that matter) is a good thing and now that crude is hitting $100 a barrel you guys are in for a rough time soon. I'm certainly not saying ethanol is the end all beat all solution to our energy problems, but it damn sure isn't hurting and the sooner people realize we need alot more diversity in our energy sources the better off we'll be.
