QUOTE : She watched a squirrel watching her. “Yeah, laugh all you want, buckaroo. I need the exercise, and nobody invited you to watch. Whoops!” Cass slid feet first down five feet or so of the rock surface. Pathetic miniature avalanches of chalky rock trickled around her. Fifteen feet away, another squirrel joined the first on the branch of a crooked, dead tree. The soil could not nourish the tree here. But the squirrels could gather there to make bad squirrel jokes and watch the human burlesque.
