That's why I kind of like the E85 deal. Race fuel octane at below regular fuel prices.

Availability Carb conversion pump compatibility Fuel lines (replacing existing rubber with new rubber)
In your area it would be equivalent to me trying to find Diesel fuel in my area. Its around, but you have to be aware of where they are.
But currently if you ever move to a state where it is not available you have to start with square one again.
