 Yeah, this is definitely not a place for agoraphobics. You know, if you have trouble with heights, you might end up walking through this whole region looking up, not down. These footbridges, they span hundreds of yards across these chasms with roaring glacial rivers. And the people who use them are local pastoralists. They are still pushing yaks around over these snowfields. I've met people who are carrying enormous loads of hay everywhere.
