Actually, it's just off the street: there's a short retaining wall between a home lot and a parking lot along College Avenue and 38th Street, where whoever owns it (possible the homeowner) has been painting pithy aphorisms for many years.
The sign-painter appears to have a keen sense of his (or her) audience; the various phrases are usually non-partisan,* "political" in that they address general issues in an uplifting way. The current one is a nice snapshot of the general approach:
KNOW HISTORY - KNOW TRADITION - KNOW PRIDE - KNOW RESPECT.
Something of a koan, really.
ETA: It turns out the artist/aphorist is Clayton Hamilton, who retired from AT&T a few years ago, and has been painting that wall for over twenty years. He's modest about it: "'They're just
humanistic insights that everybody probably has,' says Clayton about his work. 'I have a big tapestry. I could say things that maybe people would be
interested in, maybe they won't.'" (Found in an article about his son, a local artist.) I think most of us are interested, Mr. Hamilton.
* I seem to recall exactly one in recent years that expressed support for a local candidate, a man held even by his opponents to be particularly honest and well-meaning.
