Happy Chipmunk

I went to a local park this morning to get pictures of roses and ended up with this. This chipmunk was sitting on a rock next to a small stream and stood up when he saw me. I slowly approached and he ran under a rock and around it, took a quick peak at me, and then thought he darted off. About a minute later, I saw him come up and I was ready with the camera.

Looks like he is having a good laugh. Zoom to see...
