They’re everywhere. Arrows in fluorescent orange pointing in all directions. Walking stick figures. Cryptic numbers. What do they all mean?
Beneath our feet lie underground water lines, sewer lines, gas lines, power lines, telephone lines, cable tv lines, and who knows what else. When excavation is needed, utility workers mark the sidewalks to prevent accidents.
The mysterious look of these symbols reminds me of ancient cave art. In a strange way, I enjoy looking at them, perhaps because they’re so colorful and impermanent. I don’t need to know what they mean to appreciate them.
