Well it's a toss up between seeing some unconventional hygeine practices (think food, hospitals, kids peeing everywhere...) and driving along a road through the mountains in Yunnan after a storm. There were landslides, falling rocks, waterfalls over the road and one super crazy driver who seemed to think her minibus was a 4x4. That was real white knuckle stuff.
If you had a secret room accessed through a bookcase, just like the movies, what would you keep in it?
