The natural space was so extensive that he suspected it had been enlarged from the days when Denver had belonged to the United States. He had a harder time imagining a U.S. city leaving enough space to let the deer he had glimpsed roam free.

Looking at the mixed crowds passing through the park, he knew it would be soon. For the wild animals of the streets and the human hunters that stalked the parkiands, anyway.
