It became foggy today. It warmed up and then cooled down rapidly and now there is fog. i have the doors open. i hear a symphony of fog horns. i guess i've never given it much thought, a fog horn is a fog horn is a fog horn. But that isn't true. There is a high pitched one, maybe E above above middle C, there is a G below middle C, there is F above middle C and maybe one more. One will sound and then another will answer. It is interesting to listen to. In an odd way, very soothing.
