For Expedition Everest, Martin travelled to a remote corner of south west China with Disney Imagineer Joe Rohde

The imagineer's job is to come up with concepts for new rides, and see them through from research to completion

Joe's big idea was a ride at Animal Kingdom, in Florida, based on the yeti - an animal that comes to life and scares people away from the `sacred lands' around the foothills of Mount Everest

This involved several research trips to areas where the poeple not only keep up the yeti myth - many firmly believe that it is a real creature

One of the most remote locations was the monastery at Din Guo Shan, the journey to which was bedevilled by landslides and torrential rain
