Petroglyph National Monument. Alburquerque, New Mexico.

Kilroy wuz here.

Some day, the crappy graffiti under bridges will become historical images too.

Seems like an unusually high concentration of petroglyphs. Maybe this was a school.
Maybe students practiced their designs on rocks before taking a risk on leather bags or what not.

Or maybe this ranch was a daycare. I think petroglyphs were made by young people with free time on their hands. Kids like to draw and their drawings suck. Adults have too much work to doodle on rocks.
