Somehow we got on the topic of San Francisco today at work (and the "treat" that is Rice-a-roni) and I remembered this:
Skip to 4:45 for the "Old San Francisco" ride.

I rode this thing when I was five years old, and loved it. I was easy to impress as a pre-K I suppose.
We had a 45 rpm record of that "San Francisco, San Francisco out on San Francisco Bay..." song for years and years.

Good times.
