"I want to see the little store." Complicated wheelchair with multiple adjustments, where she evidently lives. She means the gift shop, where her companion steers her deftly. When I smile she looks away.

Man in blue, vibrant white hair, bent, moving with effort. He's staff: he wears a photo ID clipped to one lapel. The volunteer guides all say hello.

The people are overweight. Half are obese, the rest have beer bellies and hanging jowls. No-one looks happy. They move like sick people, or those who provide care to sick people.
