IN THE BUSH? If you are Chelsea Clinton and Marc Mezvinsky and you’ve just had one of the most-publicized (but yet private) weddings in recent memory, where do you escape for a honeymoon away from the prying eyes of the paparazzi?

While a spokesman for President Clinton declined to comment Monday, speculation is the couple is on safari in South Africa, which, if true, would make perfect sense. First, few people would recognize them in South Africa. And second, what paparazzi is going to risk being attacked by a lion or rhino just to get a photo of the couple?
