What do societal "tattoos" have to do with graffiti carvings???
More likely this ill advised carving relates to the current underground "war" between the Park service Rangers and the numerous illegal Rock Climbers who flock to do climbing stunts captured for posterity and profit on video on the Arches
Wow. That's a stretch.
Both are anti-social.
... tattoos, or skin-art, if you will, are widely accepted...
