Picking Up Poop Even When It's Not Necessary

I took my dog for a walk in a deserted campground today.

We're going through the place where there are sometimes 300 campers and tents. But now there's none. It's completely wide open. Nobody there. The attendant is long gone. The newspaper machine has a September newspaper showing through the window.

It's so bare even sagebrush avoids it.

So there we go, walking across a deserted campground. My dog takes a poop. I think, Why am I cleaning this up? There's not much of a good answer, but I guess I'm just conscientious. I cleaned it up.
