I just had the amazing pleasure of drafting an electric bus here in Spokane. The city's running a trial on zero-emissions transportation (and since almost all our electric comes from The Dam, it's actually pretty close to zero emissions).

I usually avoid drafting busses because exhaust and noise makes it so unpleasant, but this silent, smellless beauty was perfect for catching a little energy boost behind. I certainly hope these are in Spokane's future!
