Black Sunday is also the name given, in Disney parlance, to
Disneyland's opening day, in 1955. Much of the park was incomplete; a plumbers' strike had made Disney choose between having adequate restrooms and adequate drinking fountains (he chose the former); the asphalt pavement on Main Street was still soft; to make matters worse, the relatively small group of invited guests were joined by hundreds more who had managed to get in with forged admission tickets, or by climbing over fences. Worst: it all happened on national television.
