It is getting dark sooner and the birds aren't singing as early in the morning.
The grass isn't growing nearly so fast.
The crickets are "cricking" and the grasshoppers are hopping (and flying).
The hummingbirds are drinking their nectar like there is no tomorrow....and in a month they will be headed out.
The air is starting to get that fall feeling; I don't know how else to explain it.
There is a wonderful breeze out of the east today which makes sitting in my office very pleasant.
Yep, it won't be long and the feel of fall and the smell of wet leaves will be in the air... and the beauty of it all will be right there for you to see and enjoy.
