My wife and I came upon this sign, affixed to a utility pole, today, along Mission Avenue between Louisiana and Mississippi streets. Call me surprised, for having seen no other in our San Diego neighborhood of University Heights. So I got to wondering if a resident attempted a little scare tactic to get dog owners to clean up after their mutts. More effective: Place the notice higher—and above, out of reach, a mock surveillance camera.

I walked about several streets inspecting every sign of every kind and all others shared in common: Tiny print somewhere indicating that the thing is the property of the city. By comparison, this one’s credit is “SmartSign.com”, which sells the warning, with a stake kit, for 27 bucks on the website.
