An interesting article on what the Park Service is trying to do to repair the vandalism to and deterioration of some of the Service's oldest sites. These include contemporary graffiti in shelter caves and other habitation sites.
ah what a dilemna graffiti is and arent we grateful that historic and prehistoric graffiti (cave art, inscriptions over 50 years old) werent 'repaired' contemporaneously. and would it be vandalism to clean up ancient graffiti?
