There is something about the light in September. The air changes, as well as the angle of the sun. Things are now incandescently beautiful. Mornings and “the gloaming” are particularly amazing. I wish it could be like this all year round. Although, it may not be as special if we had it all the time.
I am thankful each for each day that I get to experience this.

I feel very much the same way.
Also, the air just after snowing is invigorating for me.
