You must live, or be from Southern California. The term "Frisco" is an insult to those who live in Northern California. LOL I found out the hard way when I moved from So.Cal. to Sacramento. There it is referred to as "The City" or "The Bay area".
That's a great walk you did! One of these days when I'm visiting my friends in Sacramento, I think I'll talk them into walking across the Golden Gate Bridge. Scary for me to be sure.
