There is a news story this morning about a tiger attack at the San Francisco Zoo yesterday. One young man was killed and two others were wounded by an escaped Siberian tiger named Tatiana. One disturbing part of the story was that apparently there was nothing wrong with the door to the enclosure. So the 300-pound tiger must have climbed or leaped out over the fence or 15-foot moat.
At my house here we have 5-foot rod-iron fences that do *nothing* to keep out the wild coyotes. I do not have dogs, but I have found dog-type feces in the backyard on occasion, as well as disemboweled rabbit carcasses. Also, the next-door neighbor witnessed two coyotes attacking and consuming a neighborhood cat in her backyard (I had warned the owner previously not to let the cat go outdoors). The point is made to me that my kids are not safe in my backyard, even though we live in a suburban environment. Now we are not safe going to zoos. It's not safe to swim in the ocean (sharks). I don't think we are at the top of the food chain anymore. :-(
