Is It Fall Yet?

I noticed the difference as soon as I opened my eyes this morning.  The quality of light seeping into my consciousness was purer somehow.  When I went out to get the paper, there was a clarity to the air which I haven't seen in many months.  Granted, it was subtle, but throughout the day my brain kept registering sharper images.  Late this afternoon, while coming out of the laundry room, I was absolutely positive I saw fall.  That's Fall with a capital F.
