I've found a B100 station in Salem, OH (Youngstown area) that I have contacted to confirm they can fuel my car. I'll call them again this coming week to re-confirm and to ask their current price.
For me Salem is right about my driving range limit and 2/3 of the way to Mason. Meaning I'll be nearly empty when I drive through there on the way back home to fill again for the final leg.

If you are coming down I-71 from Cleveland to Columbus, stop at exit 151 and try the Sunoco station on the West side of the exit. (sign on highway indicates Biodiesel available) On my way home to Cincinnati from New York tonight I snap this pricing photo on the 'renewable fuels pump.'
I called Salem Oil to re-confirm and now am told that they can't pump into the road vehicles due to road tax not being paid. They can pump into jugs, and the tax liability for where you use that fuel is then yours.
Even though no tax is paid it's presently $5 per gallon.
And now they will not be open Monday, Labor Day.
