The folks at EPIC (Ethanol Producers Information Council) have provided a nifty alternative fuel finder mapping tool. Just put in your city, state, etc. and find stations anywhere in the US. Mind you, if you get out towards California, you’ll be running regular gas.
Here’s a description of EPIC.
The Ethanol Promotion and Information Council (EPIC) is a nonprofit
alliance of ethanol industry leaders who have come together to grow
consumer demand for ethanol energy through targeted marketing. Our goal
is to reach consumers and key influencers across the country and
educate them on the performance and environmental benefits of using an
ethanol-enriched fuel in their automobiles.
