The enormous, blinking radio tower on Twin Peaks is half-hidden in mist, as it usually is this time of morning. And the N Judah streetcar rattles and squeals in and out of the tunnel below every fifteen minutes or so, as it routinely does, except on weekends and holidays when the intervals between trains are longer. I have woken to its sound and fallen asleep, often late, to the last train in the very early morning, for nearly 38 years now. Much else has changed around me here, but these two, the streetcar and mist, have not. I suppose they have become more a part of my identity than I realise.
