Impressive Paucity of Imagination

I recently returned from a work trip to San Diego.  As usual we were fairly busy so I didn't get much time to look around.  One thing I did notice though was how rubbish the good citizens of San Diego have been in naming their streets.  I know it's fairly common in American cities to number streets, and San Diego certainly has plenty of those, but I've never seen streets that are just single letters.

I mean, come on San Diego, you can do better than that, surely?
