SAN FRANCISCO – It’s 7 a.m., and I’m standing on the edge of a train station staring out at a field across the tracks.I’ve stayed up to this point in the morning more in the last 10 years than actually waking up at it, so the combination of Red Bull and coffee pumping through my veins has me slightly zombified – I’m awake but not really there, and my perception of what is going on around me is distorted. The horn sounds. There’ s a chiming.
