Some roads in South America are noted for their zigzags with good reason. You simply don’t want to take the fast way down. Here are a couple. The first is the main highway from Santiago that crosses over the Andes and takes you to Mendoza. Raeski took this photo from the bus window. The second dirt road takes you to Machu Piccu. If you are like most, you wish the bus driver would take it a little slower.
