I read in our local paper about the clean cities coalition and local farmers growing soy and getting fuel back. I sent an email to the caolition and got a reply w/ sites in VA that have alt fuels (b5, b10, b20, CNG etc.)
here's an excerpt;
Also, on our homepage we have a table of all alt fuels stations in Virginia. http://www.hrccc.org/. It's about halfway down the page.

I went to the Naval Air base Oceana and filled up w/b20. a little more expensive but within 10 miles I could hear it running just a little bit smoother. PLUS I know for sure that at least 20% of what I bought isn't going to Shiek yarbuti or his brother Abdul Blowmyselphup
