Ethanol Arrogance.
The first time I gave more than a passing thought to ethanol as an alternative fuel source was when I was driving from Pennsylvania to Idaho last summer. I drove for four days, and it seemed to me a good portion of the time I was driving through corn fields with signs posted every so often identifying them as destined for ethanol production. That was right in the middle of the China food and toy scare, and almost as an aside I found myself wondering why we were growing all this corn that we wouldn't be eating. Why not have the Chinese grow the ethanol corn and have us grow our own food so we wouldn't have to check the labels on everything we eat?
Somewhere in the middle of my four day spree I filled up my motorhome with 10% ethanol fuel...not too much later I vapor-locked because of that self-same ethanol and lost an hour of travel time waiting for the engine to cool down.
Needless to say I was unimpressed with ethanol.
