I've been telling students in my field methods class that we're so surrounded by texts, we don't even notice them. I've suggested that they take a walk around their neighborhood and notice the texts - and think about how different the neighborhood would be without them. Normally I think of street signs, street numbers, and other permanent texts.
But the other day I was walking in my own neighborhood and saw these temporary texts spray painted on the street. One looks like it has something to do with a telecomm company; another seems to delineate property lines and/or water meters; the third, I'm not sure. They're not meant for the general public; they help some service workers navigate the streets to do their work. I'm constantly intrigued by little traces like these, little traces that indicate other overlapping activities of which we know little.
