Gas Tax Articles

Hey guys, here are the links I have so far for the gas tax papers. I'll update them as they come in.
First, one asking is ethanol the answer?. Second, an article on hydrogen fuel (use internet explorer--something pops up). And, finally, check these links for three articles--one on how high oil prices might help the economy, another on ethanol and the environment, and an oil tax article from the NY Times. Enjoy!
