As a parent this would absolutely terrify me. Here in Southern California we've encroached on the habitat of coyotes, cougars and bears. We hear the stories, we've seen the morning news cover bears in back yards but this is uncomfortably close.
Watch as 5 Year old Christine checks the mailbox to see if her Halloween costume has arrived. Skipping back up her driveway a wild Coyote appears and then begins to chase her around the yard. How did she escape?
