What I remember most is the heat & humidity. During the parade on Saturday, I saw a bank sign reading 100 degrees at 10:05 am. That is burned into my memory.
As far as the Orange Bowl, I remember the weird field. To provide a better view of the performances, the field was move closer to the stands. The front 10-15 feet of the competition field was Astroturf while the rest of the field was grass. Had to be aware of the seam where the carpet met the grass.
