Whenever I see a grouping of contrails in the sky like I saw on the evening I snapped this picture outside my apartment building, I can’t help but think of a quote or song lyric or something some said, that these trails were “like guitar strings in the sky”.  I don’t remember exactly where I heard it, but for some reason I think it might have been my 4th grade teacher Mr. Poirier who told us  in a story before he played the class a folk song on his guitar (like One tin soldier or Flowers are red), or I could be just making it all up, but it seems far too poetic for me to come up with.
