Arriving Fall?

From Sunday's morning walk, you'd think it was still Spring time.

But, by the late afternoon, temps had dropped to the low 60's and rain was on it's way.
So, we put on our AK light rain gear and went on a walk.

Colors are slightly changing, just in the last day.
The aspen have gotten a little lighter green.

And the grass, by Sunday's afternoon rainbow,

has taken a brownish tinge.

Seems like Colorado knows that September has arrived.
