Okay, I'm normally pretty skeptical of government employees, but I've got to hand it to the City of San Diego: creating street signs in Klingon was a thoughtful and prudent touch for Klingon-speaking tourists attending Comic-Con.
The lower sign, which is Klingon transliterated into the Latin alphabet, is probably for people who speak Klingon as a second language, but would like to hone their fluency.
