It was a simpler time: Children's TV stars, pols in swank cars, and of course Dick Clark. (Someday our great-grandchildren will see an ageless TV jock leading parades and counting down the new year. My guess: Ryan Secrest, the evolutionary Dick Clark. I'd say the odds are non-trivial that they'll see another Mayor Daley lead a Chicago parade once again. I just hope they're lucky enough for cars with fins to make a comeback.)
Simpler except for maybe the clowns. As the narrator notes, they're pretty creepy, no less in shadowy Zapruder-esque home-movie footage.
