The sun is just edging above the tops of the taller trees at Love Park, and loping along at a good pace, Lisa and Auguste have almost reached the halfway mark of the five mile loop, when a small rabbit scurries across the path. “Aiyee!” yelps Auguste, and he pulls up short.

“What is it?” Lisa asks. “Don’t tell me that little bunny frightened you. You’d think you saw a bear.”

“No, it’s—it hurts.”

“Did you twist your ankle?”

“Something in my shoe,” Auguste grits teeth. “Hurts like—” He sits on the path and pulls off his shoe. Then his sock. Lisa kneels before him and examines his foot. “Looks like some blood. But otherwise...” She picks up Auguste’s discarded shoe. “Aha! Here’s the culprit.” She shows Auguste the nail. “Inch, inch and a half,” she says. “I wonder how far in it went. Anyway, you’ll have to get a tetanus shot. Do you think you can walk to the car?”
