What is that Travelocity Roaming Gnome all about?
Travelocity's gnome is based on the prank of kidnapping gnomes and sending them around the world to be photographed in locations you could only wish to visit. Thor, I believe that's his name, even won the Association of Travel Marketing Executives (ATME) ATLAS 2008 Best Overall Branding Award. He even has his own blog!
