I know of our local biodiesel supply ( http://www.distributiondrive.com ), however I do not have a diesel car. Does anyone know where I can fill up my car with ethanol? :D

Here is a link where you can find ethanol E85 fuelling stations around the country.

Just click on any state.

But you are right, it looks like there is none in Texas.

Well it's a start. Thank you very much.
Maybe I should start some serious letter-writing to state officials, senators, and fuel distribution companies.
