And so the blog has gone silent for awhile because I signed up for a writing class, and it is kicking my rather large behind. The only thing I can offer is this video that I took coming home from writing class. In this direction, Caltrain actually drives in reverse so I can look out the front (which is the back). Does that make sense? No. Okay, let me try again. The engine is at the back of the train and the engineer is pushing the train to South San Francisco from Palo Alto.
