Honorary streets are popular in many cities--New York has Joey Ramone Place (E. 2nd Street at The Bowery) and Peter Jennings Way (66th Street between Columbus Avenue and Central Park), San Francisco has Lawrence Ferlinghetti Way (near City Lights Books), and Chicago has Bob Fosse Way (Montrose and Paulina), to name a few.
Now it appears that Oakland, California is honoring corn syrup with a street sign. The one below is on Telegraph near the Berkeley border; another one is on Telegraph a few blocks to the south.
OK, I'm sure it isn't an official act by the city of Oakland, so it must be the work of artists, viral marketers or pranksters. Or could it be hip-hop musicians? My Google news alert for "USDA" frequently brings me news about a hip-hop group called "USDA." Perhaps they have a spin-off group called "Corn Syrup."
The lettering is similar to Coca-Cola's logo, so are the creators commenting on Coke's corn syrup content? If so, they would be interested in a blind taste test held by the SF Chronicle of sugar-sweetened Coke from Mexico and HFCS-sweetened Coke from the U.S. All of the tasters found the taste of the two versions to be very different, but some preferred the sugar version, some preferred the HFCS version.
Chicago has also had unauthorized honorary street signs that make some serious points about urban life, with signs like "Yes, this is the corner where they filmed High Fidelity Way" (Honore and Milwaukee) and "You paid how much for that? Way" (Oak and something).
