Yes. To depots. Trucks are still used deliver gasoline to the final destination. And those pipelines do not deliver all the different manner of refined products through the exact same pipe. Whenever a new refined product is introduced, the new pipes must be laid, in order to deliver that product to the depot. This is true whether you are talking about Ethanol, Petrol, Kerosene, Jet Fuel, Natural Gas, or anything else. Mixing 93 octane gasoline, and asphalt oil, would be nonsense, and financially untenable for the oil companies to do. Also, corn can be grown anywhere, like directly at a refinery. While the majority of corn is grown in the corn belt out in the Midwest, and the majority of Ethanol refineries are located there, it is more financially tenable to build small refineries all around the country, than to lay 95000 miles of new pipelines. Concentrating on whether it's delivered by truck or pipeline to fuel tranport depots, is just something to bitch about, and avoids any intellectual conversation about the validity of Ethanol as a fuel source or supplement. It's a very small problem, that can easily be resolved with some minor engineering.
