Memorable lines and long waits:
DMV in LA (Hollywood) and here in the Constitution State. And the emissions testing places here when they were run by the state. Man, those were primitive days. (Now that all kinds of car places can do it, it’s a breeze.)
Movies: The Godfather, The Exorcist, Jaws, E.T., and The Last Temptation of Christ always come to mind. There are surely a few I’m forgetting.
Various attractions (and eating venues) at the Disney parks, both California and Florida.
King Tut exhibition at LACMA in the late 1970s.
And leave us not forget the gas shortage lines in 1973 and 1979.
