When you're away from home, you can find yourself missing some pretty odd things. Things that others might not even notice or, if they do notice, would probably find unattractive or just strange. I miss trolley wires when I'm away from San Francisco. They make a very distinct sound when a MUNI streetcar or trolley bus goes by. An echoing, whip-tail sort of sound. It's something you might hear in a science fiction film. I hear it all day and night and when it's not around I really do miss it. Sure, the wires block out the blue skies, but they're, somehow, quite comforting. They power the things that take you places and they make it possible for you to not have to listen to the roar of a diesel engine, smell its black smoke or watch that black smoke curl up into that blue sky.
