We must confess, celebrity gossip is right up there with chocolate, shopping, and Saved by the Bell on our list of guilty pleasures, which is why the new book "My Favorite Place on Earth" has our attention. Jerry Camarillo Dunn, of National Geographic fame, premises the book on one simple question posed to a wide range of celebrities, "What is your favorite travel discovery?" We don't want to divulge too much, but a snippet of the vastly varied responses includes: Jerusalem for actress Natalie Portman; Kauai, Hawaii for Matt Groening of "The Simpsons;" Runyon Canyon Park in Los Angeles for dog whisperer Cesar Millan; Trinidad for basketball hall of famer Kareem Abdul-Jabbar; and Monument Valley on the border of Arizona and Utah for George Lucas, "Star Wars" creator. Other celebrities profiled in the book include Sandra Day O'Connor, Robin Williams, Morgan Freeman, Buzz Aldrin, Sally Ride, Jean-Michel Cousteau, Donald Trump, Jerry Seinfeld, and the Dalai Lama. The celebrity contributors not only provide their favorite destinations, but also contribute a few pages describing the special appeal of each place. Thanks National Geographic for merging our number one guilty pleasure, celeb gossip, with our biggest pleasure, travel. It's a perfect combo. And we sign off for the weekend contemplating, what is our favorite place on earth...
