Circlevision 360 had a few different versions. The one you remember had a San Francisco part and a fire truck that went through the streets of Los Angeles, among other parts of the country. It was in Tomorrowland, where Buzz is now.
Eddie: You mean to tell me you could have taken your hand out of those cuffs at any time?
Roger: Not at any time. Only when it's funny.
There were a few shown in the Tomorrowland Circle-Vision theater that I remember. Of the 2 America ones I recall, there was American Journeys, and America the Beautiful. I think the fire truck (a hook and ladder) one went through Westwood, near UCLA in America the Beautiful.
The future of telecommunications was the theme, lol. Great show and I always love the San Francisco scenes the most. For a while parts of the old show would be shown to entertain guests waiting for the Rocket Rods.
