Well, I've already got a co-driver, and I believe he'll enjoy the event, and learn how to hypermile. Plus, sitting in a car by yourself for eight hours is half as much fun as the alternative.
There's also the fact that we WILL be competing against non-ecomodders. Probably me more so than others. Look at this image Bob mailed us:
Three Honda Insights! Plus mine which will park with the EcoModders, makes four Honda Insights! I wonder who owns the other ones.
