I found this in some junk at my parents' house. It must have come from my grandfather one way or another.
This ad from 7/28/74 features the "new" collapsing bridge at Universal. I remember when that thing was the biggest deal on the tour. When I was older and working on the lot, I used to "borrow" the company golf cart to go do some "work" and give myself a little self-guided tour. It's amazing where Universal security would let one wander pre-9/11. It was a great day when I discovered the long-lost road to Prop Plaza. Never had the nerve to drive through the Six Million Dollar Man revolving avalanche thingee or across this bridge, but a visit to the Psycho house was always a must.
Love the old trams. The image of them crossing the bridge makes me think of Albert Brooks' trip to hell if he'd been just a couple of minutes late for the tram to heaven.
