Oh, now I do.  It is everywhere.  And you don’t actually have to use your ears to hear it.

If you were at the British Bash on Saturday you already know the sound of a collective “Ahhhhhh.”

It is the sound people make on a hot day and they have a cold one.  Or reach the top of the mountain and look out and see forever.

If you look at the photos below---you can ‘see’ it.  If you were there---you heard it.
