 So while you were walking in this area, you posted some amazing pictures of foot bridges crossing rivers that cut through the mountains. They look a lot of fun and a little terrifying to walk across. Tell me about the people who use those every day, the people who live in this region. 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 foot bridges, they span hundreds of yards across these chasms with roaring glacial rivers.
