e85 in IA?

[dogwhistle]

Lol true. I've done this trip and dozens of 1000+ mile road trips, but never in a vehicle requiring e85. I will have my laptop with me to make ECU changes if absolutely necessary but I just thought I'd lay out a route that doesn't require bringing extra fuel for safety and convenience. Also, politics more than geography play a role in what types of fuel are available...
