Kleitsch was the only scheduled protester who had showed up that Tuesday. On one officer's schedule for the day before, ten groups were slated. Nine had "no show" written in red ink next to their names. The Greyhound Adoption Program had shown up.

"It's bring your own audience," one plainclothes officer said.

A woman walking with her son through the park, said she had been moving along the fence for a half-hour, trying to find a way out. Several police had sent her to the enclosure, and told her police there could let her out. They could not.

"There's no way out? It's me and my three-year-old and we're stuck?" she asked police.

They directed her across the fountains and gazebos to the 20th Street entrance, and she started with child in tow.

Two police roared past her on dirt bikes, heading for a young man who had stepped off a path onto the grass. They slid the bikes in front of and behind the boy, and told him sternly, repeatedly, to get back on the gravel trail.

"Where's the Swedish-American Museum?" he asked the police.

They both gestured at the trail, he complied, and then the police took off into a grove of trees.
