There's a race-grade ethenol blend available at the NCM Motorsports Park. Beyond that, E85 is pretty scarce in Bowling Green. There's on station at 3208 Scottsville road showing up at e85prices.com. But I don't know first hand if that station still has it or not. It's also showing two stations in Elizabethtown, which is halfway between Louisville and Bowling Green.
And we have almost thirty stations with it in Louisville. So you can grab some on your way in.
