Early morning in Yosemite. I took walk. Morning air was somehow clean. 
But we have a lo of smoky air from wild fire noontime to evening. 
It was the first day of Yosemite watercolor class.
I was concerned about the condition of the air.
Because It is pleine air watercolor class.
I had five students at the class.
It was pretty good number, after all trouble we had day before
such as wild fire, highway closing, road congestion.
