On my way to east Bismarck on Wednesday, I came over the hill by the Coke plant to see the whole area awash in a foggy haze. I thought it truly was fog until I saw this:

The DMVW railroad was warming up a couple of diesel-electric locomotives. There were actually two pairs but only this pair was smoking. I wonder who checked the oil? You could check it by sticking a finger in the air. It smelled like it was synthetic, too…that can’t be cheap. Or environmentally friendly!
