The other night I had an incredible experience,just being outside in my own back yard,watching the clouds and the moon,and feeling the warm breeze that had iust a hint of fall in it.I WaS perfectly comfortable and spellbound by the show the clouds were putting on,as if in time lapse photography.Low clouds were flying by at an unusual speed as they passed between the nearly full moon and the silhouette of the apple tree nearby.Directly overhead was a margin in the sky where two zones interfaced.On the right towards the ocean was the incoming marine layer being swept northwest by the warmer,drier wind from the desert.
