"Leave no trace."

I've driven 200 miles out of my way to look at Anasazi rock houses, rock paintings and Register Cliff (near Guernsey, WY), where many of the pioneers carved their names, initials and dates they passed on their way to CA, OR, etc.

I've also stopped at campgrounds and walked through with a plastic bag, picking up the debris of previous campers. Should I have left it as I found it?

"Pack out your trash" would seem to be a better motto to pass along.
