On the sign

Stacked to the right of a large "NO" as tall as the four prohibitions were "open toe shoes," "loose shoelaces," "food or drink," and, I think, "running," although it could have been standing.

"You must be as tall as me or with a big adult." At many amusement-ride setups, there's merely a bar set at the height.
