Graffiti?

 The dogs were barking. Looking out the front window I saw three people spray painting on our city sidewalk near our fireplug. By the time I grabbed the camera, they were across the street, doing the same thing with a stencil.
They did both corners and then the two women and two old hippies took off north down the street.

I'll show you tomorrow why they were using paint to deface the sidewalks.
