It seems some neighborhood squirrels were jumping from rooftop to rooftop chasing one another and playing leap frog on the privacy fences between lots. There were five of them running back and forth, jumping and seeming to have quite a good time.
I believe the sudden appearance of me and my camera outside interrupted their play. One of the group sounded the alarm and all motion and noise ceased for a bit. I was able to take a quick picture of this squirrel taking a break in the neighbor's aspen tree.
He looks quite cozy there, though also aware of my presence.
As soon as I headed back inside, all the squirrels were all at it again...
