Sometimes they sneak in there...
But not very often...People and obvious signs of human presence are sometimes included as a delibrate part of the image (silly me -- everything in my images is included on purpose). Except for the series of my boys in the environment, I have included "strangers" only once in a finished print...though I have included signs of human presence (roads, buildings, etc) more often.
