Vintage Car Passing By, Only in San Francisco!

I was coming home from Chinatown this afternoon and was walking along the end of Jasper near Green St. in North Beach- when I chanced upon the sound of an antique car approaching into my direction. I can see it clearly from my vantage point. Just as it was pacing to cross Union and Jasper,  I was able to capture  it in full site through my iPhone. The car came by so quickly. In a minute, it was gone!

The driver was in his 40s and the passenger, an elderly man, in his 70s, obviously was having a ball! Now where in the world would you see something like this? Only in San Francisco!
